Indeed. The PTO is rather harder to parse, but in general, on Jan 1, 1943, Army Ground Forces (AGF) comprised 1,940,000 troops, Army Air Forces (AAF) comprised 730,000 troops, Army Service Forces (ASF) comprised 2,730,000 troops. On Jan 1, 1944, Army Ground Forces comprised 2,550,000 troops, Army Air Forces comprised 1,170,000 troops, Army Service Forces comprised 3,865,000 troops.
Actual breakdown of divisional vs non-divisional personnel in Army Ground Forces was about 45:55, so on Jan 1, 1943, only 875,000 troops were in divisions (out of 1.94 million in AGF and 5.4 million total USA)). On Jan 1, 1944, only 1,150,000 troops were in divisions (out of 2.55 million in AGF and 7.6 million total USA).
In-game, there are no ASF units. Only about 25% of AAF personnel are represented. Only about 35% of AGF non-divisional personnel are represented. So on Jan 1, 1943, the game is short about 700,000 AGF non-divisional personnel, about 500,000 AAF personnel, and 2,730,000 ASF personnel. That's 3,900,000 shortfall out of 5,400,000. These are US Army totals and, of course, the PTO numbers were much smaller. However, the relative percentage scales should be similar.
The whole point is that IRL troop density might be interesting on an intellectual level, but it has no intrinsic relevance to "game" troop densities. One needs to scale IRL densities down by a factor of 3 or 4 to get to 'game" densities.
