[MCU] Did Captain America's existence change the military compared to ours or was he just another war hero (I.e. not unimportant but the military industrial complex just keeps on rolling)?

He showed a way of warfare (small regular human squad led by superhuman captain) that seems to have impressed the military and that they seem to have loved to keep going (based on all of the super soldier experiments that continued on after his supposed death at sea, even into recent times with Bruce's attempt and the centipede project stuff in Agents of SHIELD). But, since the serum was never stable enough to go into production, they mostly had to rely on regular old tactics.

So, while there was certainly a good amount of government money put into redeveloping a super soldier serum, it never fully eventuated and so by necessity a lot of the modern military developed the same as if it was a world where Captain America never existed.
