Strategy Page gives a nice overview of the Canadian introduction of tanks to the Afghan war:
Canadian use of Leopard 2 tanks in Afghanistan convinced the brass that these Cold War era vehicles are valuable weapons for irregular warfare. Immune to most enemy weapons and possessing enormous firepower, the heavy tanks were very useful. In light of this experience with the Leopard 2s in Afghanistan, Canada has bought 100 Leopard 2A6s from the Netherlands and another 20 2A4s from Germany. The last twenty were modified for operations in Afghanistan (better protection against mines and roadside bombs).
It was three years ago that Canada bought the hundred second hand Leopard 2 tanks from the Netherlands, to provide their troops in Afghanistan with some additional combat power. First, they leased 20 German Leopard 2s and sent them to Afghanistan to replace the older Leopard 1s. Initially, crews for the Leopard 2s trained on the elderly Leopard 1s in Canada, before going Afghanistan. There, they have to quickly familiarize themselves with the slightly different Leopard 2s. But now there are sufficient Leopard 2s in Canada for training.
It was four years ago that Canada sent 17 of its Leopard 1 tanks to Afghanistan, to give Canadian troops there some extra firepower against the Taliban. But during the Spring and Summer, the lack of air conditioning became a major problem for the crews. The age of the tanks was a factor as well, so Canada has made arrangements with Germany, the manufacturer of the Leopard, to lease twenty of the most modern version of the tank, the Leopard 2A6M (which had enough room inside to install air conditioning).
Canada is the last nation using the Leopard 1. The A6M has considerably better protection against mines, roadside bombs and RPG rockets. The 62 ton Leopard 2 has a 120mm main gun and two 7.62mm machine-guns. The 43 ton Leopard 1 has a 105mm gun, and is actually a little slower (65 kilometers an hour) than the Leopard 2. Both tanks have a four man crew.
Being the last major user of older technology is a familiar place for Canadian soldiers to be. We were also one of the last nations to retire the Centurion tank, and back in the 1970’s, it was quite common for all the vehicles in a unit to be older than almost all the troops in the unit. I got my military driver’s license on a jeep that was more than twice my age, for example.
