Even without taking the adverse reactions and the loss of troops to the vaccine mandates into account, the US military does not have the capacity to fight a war against both China and Russia:
Capacity Score: Weak
Historical evidence shows that, on average, the Army needs 21 Brigade Combat Teams to ﬁght one major regional conﬂict (MRC). Based on a conversion of roughly 3.5 BCTs per division, the Army deployed 21 BCTs in Korea, 25 in Vietnam, 14 in the Persian Gulf War, and approximately four in Operation Iraqi Freedom— an average of 16 BCTs (or 21 if the much smaller Operation Iraqi Freedom initial invasion operation is excluded). In the 2010 Quadrennial Defense Review, the Obama Administration recommended a force capable of deploying 45 Active BCTs. Previous government force-sizing documents discuss Army force structure in terms of divisions and consistently advocate for 10–11 divisions, which equates to roughly 37 Active BCTs.
Considering the varying recommendations of 35–45 BCTs and the actual experience of nearly 21 BCTs deployed per major engagement, our assessment is that 42 BCTs would be needed to ﬁght two MRCs. Taking into account the need for a strategic reserve, the Army force should also include an additional 20 percent of the 42 BCTs, resulting in an over-all requirement of 50 BCTs.
Previous editions of the Index had counted four Army National Guard BCTs in the overall count of available BCTs. Because the Army re-ports that no Army National Guard BCTs are at the highest state of readiness, they are no longer counted in this edition of the Index. The Army has 31 Regular Army BCTs compared to a two-MRC construct requirement of 50.
Granted, it’s a neocon-funded study by the Heritage Foundation which is almost certainly intended to justify increased military spending, but that doesn’t change the fact that the number of Brigade Combat Teams available now is only sufficient to address one major regional conflict, and there is no chance that either China or Russia are going to permit the USA to play divide-and-conquer any longer.
