I believe you are incorrect about the US Army’s percent of the federal budget. Total defense spending (all branches) represents around 15% of the budget.
Ah, great catch! I’m admittedly nowhere near an expert in this regard. I was looking at the US Discretionary spending budget, and mistakenly thought that was representative of the total budget
I was looking at the discretionary budget breakdown: https://www.pgpf.org/chart-archive/0070_discretionary_spendi...
