I thought a "basic load" was actually 200 rounds of ammo. That's what it was when I was an infantry officer. Is it different for support guys? What about sidearms? What's that basic load?
It was 5 magazines of 20 rounds, now probably 5 magazines of 30 rounds - 150 rounds available. Even with a couple extra mags, it wouldn’t last long. Mechanized infantry has the means of acquiring and carrying a lot more - the tracks can hold a lot.
