… the tank was a direct response to the battlefield conditions of WWI, in particular the trench stalemate on the Western front. The idea of some kind of armored “land cruiser” (potentially armed with machine guns) had been floated before WWI but never seriously considered and developed on, but serious development only began in 1915 with the formation of the Landship Committee early that year. Famously, they needed a code-name for their planned vehicle and opted first for “water carrier” and then for “tank”, thus giving the tank its peculiar English name.
And we should stop to note that as with any question of definition, this one too is language-sensitive. The exact confines of a term vary from one language to another; kampfpanzer, for instance is not necessarily an exact synonym for “tank”.
In any event, the basic demands of early tanks were dictated by the realities of the Western Front: a tank needed to be able to resist small arms fire (particularly machine guns), deliver direct supporting fire itself, it needed to be able to move on the muddy, artillery-flattened ground and it needed to be able to cross a trench. This last requirement – the need to be able to both climb a parapet (usually c. 4ft) and then cross over an 8ft wide trench – was significant in the design of early tanks.
Those factors in turn dictated a lot of the design of early tanks. The armor demands of resisting small arms fire meant that the vehicle would be heavy (and indeed, as soon as tanks appeared amongst Allied troops, their German opponents began introducing more powerful bullets, like the K bullet and later the 13.2mm anti-tank round fired from the Mauser 1918 T-Gewehr). And here is the first advantage of tracks. The weight of a vehicle is distributed along all of the area of contact it has with the ground; with tires that area is limited to the bottom of the tire so the total area of ground contact is fairly low, which is fine for most vehicles.
But tanks are heavy. Really heavy. Even something like the Renault FT could mass around 7 tons and by later standards that would be classified as a tankette (a “mini-tank” as it were); by WWII, medium tanks often clocked in around 30 tons. If you put a vehicle like that on tires, you are going to create a LOT of pressure on those small points of contact. That might still be OK if you are just going to drive on roads and other firm surfaces which can take the pressure. But remember: tanks were designed for the Western Front, which looks like this.
Fortunately for the landship committee, this wasn’t a new problem: farming tractors were also heavy and also had to operate in churned up (in this case, plowed) soft soil; the heaviest of these vehicles had much the same problem and the solution was continuous tracks or “treads”. When kept properly tensioned – tune in, by the by, to Nicholas “The Chieftain” Moran’s YouTube for more than you ever want to know about track tension – the track distributes the weight of the tank across the entire section of the track touching the ground, which reduces the ground pressure at any given point, allowing a big heavy tank to roll over terrain where even a much lighter wheeled vehicle would get stuck.
This is one of those points where the functionality of a tank (what a tank does) has such a strong influence on design that the design implications of the functionality become part of the definition: a tank has to be heavily armored and has to be able to move off-road and as a result has to be tracked, not wheeled. One might be able to imagine some sort of exotic technology that might make it possible to do all of the things a tank does without tracks, but we don’t have that yet.
The other factor was fire. I’ve mentioned this before, but one of the significant background factors of WWI is that a lot of the belligerents misjudged the kind of artillery they’d need for a general European war. Not to get too deep into the weeds here, but most of the belligerents expected a relatively rapid war of maneuver and so thought that light, direct-fire artillery like the famed French ’75 (the Matériel de 75mm Mle 1897) would be the most useful. Those guns could be moved quickly and could deliver a lot of quick firepower on static or moving formations of enemy infantry in support of friendly infantry.
The problem is that in the conditions of trench warfare, those guns – as they were configured, at least – were far less useful. They were, first off, much shorter in range which meant they had to be brought dangerously far forward to do their direct fire role – often so far forward they could be engaged by enemy rifles and machine guns. This was compounded by the fact that direct fire at range was ineffective against trench works (which are dug down into the earth). But at the same time, the value of rapid firing (because these lighter guns could fire a lot faster than the heavy, indirect fire artillery) direct fire artillery remained high, if only you could get it to the fight.
This was also a problem a tank could solve: as a mobile, armored platform it could move a rapid-firing direct fire gun forward without immediately being knocked out by enemy small arms to support the infantry. There is, I should note, early complexity on this point, with both “male” (heavy direct fire cannon focused) and “female” (machine gun focused) tanks in WWI though in the end “hermaphrodite” designs with both capabilities (but much more focus on the main cannon) triumph, so that’s what we’ll focus on.
And that gets us the fundamental role structure for tanks: enough armor to resist enemy small arms (but with the understanding that some weapons will always be effective against the tank), enough mobility to cross the churned up battlefield and some direct fire capability to support the infantry crossing it at the same time.

Fighting at Yenangyaung, 17-19 April 1942
Dr. Robert Lyman on the battle at Yenangyaung between 17-19 April 1942 early in the Burma campaign:
… the Yenangyaung battle is a fascinating one, with its own small degree of controversy, I decided to lay it out in this post. A mystery of the battle is the differing accounts of the Chinese attacks on the 19th April. In the British accounts (including Bill Slim’s in Defeat into Victory) the Chinese are blamed for failing to attack in the morning as they had promised, adding further jeopardy to the fate of the encircled 1st Burma Division. But was this true? The Japanese, Chinese and American accounts differ, so I thought I’d lay out the story to allow you, dear reader, to come to your own conclusion.
The scrap at Yenangyaung was the final Corps-sized battle before the order to evacuate Burma Corps was given in early May. The Japanese had pushed out of Rangoon in mid-March, driving up the Irrawaddy on the left and against Toungoo on the right. Allied plans for the defence of Burma were inadequate, both Chinese (on the right) and Slim’s Burcorps (on the left) effectively fighting separate battles. Attempts by General Harold Alexander, the Army Commander, to control the battle and constrain the advancing Japanese ultimately came to naught. Alexander, Slim and Lieutenant General Joe Stilwell, nominally commanding the Chinese 5th Army, tried every trick in the tactical rule book to bring a halt to the relentless Japanese advance, and to destroy them in battle. After a month of fighting in which the Chinese were pushed out of Toungoo, the British lost control of Prome and an attempt to consolidate a defensive line across the country failed, the Japanese moved up the Irrawaddy in an attempt to turn the British flank, breaking in at the oilfield town of Yenangyaung on 17 April. At the time Slim’s Burma Corps was attempting to withdraw to the north from Allamyo. The Japanese infiltration into Yenangyaung cut the British in half. The 1st Burma Division was now cut off in Yenangyaung. The battle by the already weakened division (amounting to probably no more than 4,000 troops) into the Yenangyaung pocket over the period 17 and 19 April proved to be the severest trial yet faced by British troops in the short Burma campaign, the pressure applied by the Japanese exacerbated by the intense heat and the lack of water.
It was critical that Slim defeated this Japanese infiltration, rescue the 1st Burma Division from encirclement and retain the integrity of his Corps. If Yenangyaung were lost the Japanese would be free to sweep north to threaten Mandalay. It was crucial therefore that the divisional commander – Major General Bruce Scott – held on for as long as he could. But Slim had no reserve. The only hope of relief lay in assistance from the Chinese far to his right. He concluded that if he could engineer a attack into the pocket by the Chinese, across the Pin Chaung, combined with a breakout attack by 1st Burma Division, they might have a chance of escape. Nothing else looked likely to succeed.
When asked, Stilwell agreed to Alexander’s request for help to be provided to Slim, and gave him Lieutenant General Sun Lijen’s 38th Division – responsible for the defence of Mandalay – for the task. Chiang Kai-shek had given Sun responsibility for defending Mandalay. At midnight on 16 April Sun received an order from General Lo Cho-yin, “to dispatch his 113th Regiment to Kyaukpadaung, there to be commanded by the British General Slim …” Sun’s friend, Dr Ho Yungchi, recorded that by 3 a.m. he had arrived at Lo’s HQ at Pyawbe to discuss the order. Lo explained that the British were in serious trouble “in the oil town of Yenangyaung and had sent repeated requests for help”. By 6.30 a.m. it was agreed that Sun would personally take command of the 113th Regiment, while the two remaining regiments stayed to defend Mandalay. Sun and 1,121 men of 113th Regiment (commanded by Colonel Liu Fang-wu) arrived at Kyaukpadaung on the morning of 17 April.
Slim recalled: “The situation was not encouraging, and I was greatly relieved to hear that 113 Regiment of the Chinese 38th Division was just arriving at Kyaukpadaung. I dashed off in my jeep to meet their commander and give him his orders … this was the first time I had had Chinese troops under me … I got to like all, or almost all, my Chinese very much. They are a likeable people and as soldiers they have in a high degree the fighting man’s basic qualities – courage, endurance, cheerfulness, and an eye for country.”1
At Yenangyaung, Slim’s plan was for Sun’s 38th Division to attack from the north on the morning of 18th April while the 1st Burma Division, within the pocket, fought its way out. As Slim and Sun Lijen talked, discussing the details of the attack planned for the following morning Slim decided that he would place the Stuart tanks of the 7th Armoured Brigade directly under Sun’s command. It was only a move a man confident in the capabilities of his allies could make. Slim commented that “I was impressed by Sun and it was essential to gain his confidence. His division had no artillery or tanks of its own, and I was therefore arranging that all the artillery we had this side of the Pin Chaung and all available tanks should support his attack.” The commander of the British armoured brigade – Brigadier John Anstice – accepted this arrangement and according to Slim “he and Sun got on famously together”. What’s more, the soldiers worked well together too, Slim recording that the “gunners and tank crews, as is the way of British soldiers, soon got on good terms with their new comrades, and, in spite of language difficulties of an extreme kind, co-operation was, I was assured by both sides, not only close but mostly friendly.”2 Accordingly, at 6.15 a.m. on 18 April, Major Mark Rudkin of 2nd Royal Tank Regiment (2RTR) reported as instructed by Anstice to 38th Division HQ:
There was little activity except for the cooking of breakfast and it seemed most unlikely that the attack could start on time. I asked the British liaison officer with the Chinese what was happening and he informed me that as the Chinese realized that they would not be ready to attack at 0630 hours, they had put their watches back one hour, so that officially they were still attacking at 0630 though the time would in reality be 0730. They had, therefore, not lost “face” by being late.
The plan was that a troop of tanks would follow the leading troops of the leading Chinese battalion and give what support it could. Another troop was to follow the leading infantry battalion and assist the leading troop if required. The tanks would be almost entirely road bound owing to the going off the road.
At 0730 the assaulting Chinese moved forward off the ridge on a front of about four hundred yards, the leading troop keeping very close behind on the road. On foot near the tanks was a Chinese interpreter who carried out liaison between the tanks and infantry.
After advancing about half a mile the leading tank was hit by a Japanese 75-mm gun situated on the road just north of the Pin Chaung which was firing straight up 300 yards of road. The tank was disabled but there were no casualties.
The Chinese advance continued and by afternoon had almost reached the line of the ford on the Pin Chaung which was still held by the enemy. The Chinese had had heavy casualties, especially amongst officers, as it was the custom for Chinese officers to lead, whatever their rank. It was finally decided to hold positions about half a mile north of the crossing and continue the attack next day.3
With the first attack a failure, the Japanese retained their grip on both the ford and the village of Twingon. The situation for the surrounded remnants of the 1st Burma Division was desperate; the Japanese close to achieving a complete victory. Slim and Sun then worked through a plan for another attempt to be made the following morning, 19th April. This day also began badly, however. The Chinese attack was scheduled to begin at 7 a.m. British accounts subsequently recorded that a Chinese attack did not materialise at this time. Slim subsequently recorded in Defeat into Victory that the failure to attack must have been a function of the administrative difficulties faced by the Chinese. He wrote that with the Chinese “lack of signalling equipment, of means of evacuating wounded and of replenishing ammunition, and their paucity of trained junior leaders it was not surprising that to sort themselves out, reform, and start a fresh attack took time”.4 Slim was invariably impressed with what he saw of the Chinese soldier in action, but considered their support and command functions to be shockingly poor and a source of constant frustration to themselves, and to all who had occasion to operate with them.
Slim, and most other British published accounts, including the Indian and British Official Histories, record that the attack finally went in at 3 p.m., when Colonel Liu’s 113th Regiment successfully captured the ford and penetrated into Yenangyaung.5 “When the Chinese did attack they went in splendidly” wrote Slim in admiration. “They were thrilled at the tank and artillery support they were getting and showed real dash. They took Twingon, rescuing some two hundred of our prisoners and wounded. Next day, 20th April, the 38th Division attacked again and with tanks penetrated into Yenangyaung itself, repulsing a Japanese counter-attack. The fighting was severe and the Chinese acquitted themselves well, inflicting heavy losses, vouched for by our own officers.”

Why TOG II was BETTER Than You Think
The Tank Museum
Published 20 Dec 2024It was rejected and ridiculed for years — but TOG II is actually much better than you think.
In 1939, the UK Ministry of War issued the spec for a heavy assault tank. This hefty brief included the requirements to cross a 16ft gap, climb over anti-tank obstacles and enough firepower to penetrate 7 inches of concrete. Enter “The Old Gang”, a group of expert engineers, responsible for most of the tanks created during the First World War.
Two vehicles were created during this process — TOG I and TOG II. While the TOG projects have often been rejected as tanks out of time — relics of thinking from trench warfare — Content and Research Officer, Chris Copson, argues that these vehicles were highly innovative in terms of their mobility, armour and firepower.
Despite fulfilling their brief, TOG was sidelined in favour of other projects, and the lone survivor — TOG II — arrived at The Tank Museum in the 1950s. This lumbering beast that never saw active service, sat sidelined whilst surrounded by WW2 legends like the Churchill, Sherman, and the infamous Tiger 131.
But in 2012, a miracle happened. World of Tanks included the super heavy tank in their online video game — launching TOG II into viral popularity. Since then, interest in this unique vehicle has skyrocketed, and now more than ever people want to see TOG II in real life and find out more about its interesting history.

Buying military surplus is often a bargain, but buying new military equipment is usually a financial black hole
The Canadian government has — since at least 1968 — always viewed major equipment purchases for the Canadian Armed Forces first and foremost as “regional economic development” projects which channel federal dollars into vote-rich areas in need of jobs or to reward provinces and regions for their support of the party in power. This virtually always requires getting all or most of the manufacturing/construction/assembly done in Canada.
To most people this sounds sensible: big military equipment acquisitions mean vast sums of taxpayer money, so why shouldn’t as much of that money as possible be spent in Canada? The answer, in almost every case, is that it will usually be VASTLY more expensive because Canadian industry doesn’t regularly produce these exotic, spendy items, so new factories or shipyards will need to be built, all kinds of specialized equipment will need to be acquired (usually from foreign sources), companies will need to hire and train new workforces, etc., and no rational private industries will spend that kind of money unless they’re going to be guaranteed to be repaid (plus handsome profits) — because CAF equipment purchases come around so infrequently that by the time the current batch need to be replaced, the whole process needs to start over from the very beginning. It would be like trying to run a car company where every new model year means you shut down the factories, fire the workers, destroy the tools and jigs and start over from bare ground. Economic lunacy.
Items like clothing, food, non-specialized vehicles (cars, trucks, etc.) may carry a small extra margin over run-of-the-mill stuff, but it will generally be competitive with imported equivalents.1 Highly specialized items generally won’t be competitively priced exactly because of those specialized qualities. The bigger and more unusual the item to be purchased, the less economic sense it makes to buy domestically. As a rule of thumb, if the purchase will require a whole new manufacturing facility to be built, it’s almost certainly going to be cheaper — and usually faster — to just buy from a non-domestic source.
How much more do Canadian taxpayers have to shell out? Carson Binda has some figures for current procurement boondoggles:
Take the new fleet of warships being built for the Royal Canadian Navy – the River Class Destroyers. The Canadian River Class is based on the British Type 26 Frigates.
The Brits are paying between $1.5 and $2.2 billion in Canadian dollars per ship. Meanwhile, Canada is paying upwards of $5.3 billion per ship, according to the Parliamentary Budget Officer.
That means we’re paying double what the Brits are, even though we are copying their existing design. That’s like copying the smart kids’ homework and still taking twice as long to do it.
If we paid the same amount per ship as the British did for the 15 ships of the River Class, we’d save about $40 billion in procurement costs. That’s twice as much money as the federal government sends to Ontario in health-care transfer payments.
[…]
Prime Minister Justin Trudeau’s government bungled F-35 fighter jet procurement is another example of taxpayers losing out on military procurement contracts.
In 2010, the Harper government announced plans to buy 65 F-35 fighter jets for an inflation-adjusted cost of $190.8 million per unit.
The Liberal government canceled that procurement when it came to power. Fast forward to 2023 and the Trudeau government announced the purchase of 88 F-35s at an inflation-adjusted cost of $229.6 million per unit.
That massive increase in cost was totally avoidable if the Liberals would have just kept the Harper-era contract.
[…]
Because so much budget is wasted overpaying for big ticket items like ships, jets and trucks, soldiers aren’t getting the basics they need to keep Canadians safe.
The defence department bureaucrats can’t even figure out how to buy sleeping bags for our soldiers. National Defence spent $34.8 million buying sleeping bags that were unusable because they were not warm enough for Canadian winters.
Recently, Canadian soldiers sent to Ottawa for training had to rely on donated scraps of food because the military wasn’t able to feed them. Soldiers have gone months without seeing reimbursements for expenses, because of bureaucratic incompetence in our cash-strapped armed forces.
1. Note, however that during the 1980s, the Canadian army wanted to buy Iltis vehicles that were built in Germany at a $26,500 cost per unit. Getting the work done under license in Canada by Bombardier more than tripled the per-vehicle cost to $84,000.

“Britzkrieg” – Did British Tactics Help Create Blitzkrieg?
The Tank Museum
Published 30 Aug 2024Where did Blitzkrieg, the tactics that enabled Germany to conquer most of Europe in the first years of WW II come from?
Throughout the 1920s and into the ’30s, the German Army was forbidden from developing tanks or experimenting with armoured warfare, but in the same period, the British Army was at the forefront of mechanization and the use of armour on the battlefield.
In this film, we will look at how British tacticians like JFC Fuller and Basil Liddell Hart developed a new and revolutionary way of warfighting and how these principles were taken up and used to devastating effect by the German Army in 1939 and 1940.
