2700000 million Americans served in Vietnam though. There's really no comparison between back then and today with regards to labor costs and/or military manpower. The expectations for health care just rose in the last 60 years. That's where I was going with "number of explosives", because I'd expect that the "number of explosives per soldier" to be relatively constant. (Sure, weapons can get more sophisticated, but soldiers have a hard limit to what they can efficiently carry into battle). For example: a modern AT4 (anti-tank munition) is roughly the same weight as the WW2 Bazooka. This is because the weight-limits per soldier are set. I'd expect that Roman Legionnaires, Medieval Knights, and modern soldiers to have all carried roughly the same equipment weight. The AT4 is more accurate, more sophisticated and more damaging than a bazooka, but the general form factor and use is the same.
