Essentially, the armed forces are short anywhere between 13,000 and 16,000 people. To address that shortfall, it would be at least an additional billion dollars per year just for the personnel costs.
On top of that, you have the basic and advanced training requirements. Due to the lack of progress on any of the major weapons systems needed to allow our people to survive contemporary warfare—especially since the warfare examples we have in Ukraine are showing that new technologies are required, plus a whole bunch of the older ones—our armed forces are woefully ill-equipped. That bow wave of equipment acquisition is what's causing the government to step back from announcing, for example, a contract for the ammunition systems for the ships, for the planes, for the tanks, and it goes on.
