This of course forms the context for the creation of the All-Volunteer Force (AVF), the effective conversion of the United States military into a professional, fully standing military, which I’d argue is the single most dramatic shift in the civil-military relationship in American history, the full impact of which is not yet clear. For almost 200 years, the United States military had been an essentially civilian force which relied on conscription. For the decades prior to the creation of the AVF in 1973, conscription had been a fact of life. While the United States had demobilized substantially after WWII, there had been at least some conscription in every year from 1940 to 1972 except for 1947. In every year between 1950 and 1972, conscription had never been lower than at least 80,000 new conscriptions a year.

This was a huge change. For such a major change, I find that it draws surprisingly little attention. The 50th anniversary of the AVF passed with relatively little fanfare in 2023. I’ve mentioned For the Common Defense (1984, 1994, 2012) as the dominant textbook for introductory American military history: the shift to the All-Volunteer Force is dealt with in a single page (page 568, for the curious). The textbook I’ve seen most recently used for US Naval history (and which I used), J.C. Bradford and J. F. Bradford, America, Sea Power and the World (2016, 2023), doesn’t even give it that much: the shift is discussed in a single paragraph on page 351 (308 in the 2016 edition).¹

The likely impacts of the shift to an AVF were studied prior to implementation in the Gates Commission, a report that had a preordained conclusion – it was convened to provide Nixon the cover to do the thing (end the draft) he had promised to do already in his campaign – and which honestly I find disappointing in its approach, which is mostly “happy talk” designed to justify what Nixon had already decided to do. It is striking to me, for instance, that the Gates Commission did not include a single historian to perhaps discuss how the shift towards fully professional militaries had gone for republics in the past. Instead, the focus is on the economics of the shift, with fairly blithe assertions that the civil-military relationship would remain unchanged despite the fairly obvious implausibility of that given the shift from “everyone serves” to “only a small portion of society serves”.²

As I’ve noted elsewhere, the Romans also seem to have thought that they could professionalize their army without reducing its ability to scale up in an emergency or altering the civil-military relationship and for quite a few decades that more or less worked, while the old norms held. But as those old norms decayed, the institution increasingly became what you’d expect from its institutional structure: a permanent political faction, advocating for its own interests, often with violence, to the point that the emperor Septimius Severus’ advice to his sons as he lay dying in 211 was, “Be harmonious, enrich the soldiers, and scorn all other men”,³ a fairly open admission that the soldiery was not just a political constituency, but the most important one. It took time for those norms to shift, but when one is building or rebuilding institutions, the long-term is the term that matters.

I do not think necessarily that this is the direction the All-Volunteer Force must go. It has two and a half centuries of strong norms pushing it away from this direction. But careful maintenance of the civ-mil bargain is made all the more necessary when the military is effectively fully professional. For my own part, all cards on the table, while I greatly value the service of the United States’ military personnel (there’s that third part of the bargain!) and think they serve honorably, I am quite skeptical of the long-term implications of the All-Volunteer Force. Its creators assumed that fully professionalizing the military would not impact the civil-military relationship and that it would always be possible to shift back to a mass-conscript army in the event of a major war, but historical examples suggest it is not so easy.

But the All-Volunteer Force is not the direction from which I see now the principal threat to the civ-mil bargain.

1. In that book’s defense, the Navy has a really big set of reforms associated broadly with CNO Elmo Zumwalt that happen at basically the same time and are connected and it opts to focus on those. I will note that the position of the paragraph has changed because the updated 2023 version of the book has opted to grapple more extensively and more successfully with this period as one of increasing diversity in the navy, with a chapter by Kristy N. Kamarck on that specific topic. It is a marked improvement over the first edition, though I think both FtCD and the Bradford and Bradford remain too hagiographic, too willing to sweep the military’s problems under the rug and only comment on military diversity when they can tell the story as a happy tale of progress.
2. Especially as that small portion tends to be concentrated, a thing the Commission essentially refuses to consider as a first principle of their analysis; they assume cheerfully that the AVF will naturally continue to reflect a cross-section of the United States. In some ways that is true, but in other ways it is very much not – there certainly are “military families”, where service tends to “run in the family” in the United States now – and the emergence of those patterns would have been a pretty obvious thing to expect, given that the same trend is extremely visible in the Roman army of the early empire.
