"3 mags, 80 rounds..."

[Raptor]

This refers to the deleted scene where SecOps and the conscripted miners load up for the attack on the Well of Souls. However, one dumb thing struck me. What kind of SecOps idiot would think that 80 cartridges can be divided between 3 magazines? And what kind of moron would give each personnel 80 rounds? Typical load-out today is 210 rounds (many soldiers and Marines will load as much as 360). Maybe ammunition is more effective in 2154 (perhaps they're multi-firing?), but considering how they simply let loose with fully automatic fire during the battle, how are they ever going to expect 80 rounds to last?
