U all sure infantry die first??
before the enemies meet the those normal infantry... they will meet with other special group first... hence not first to die
in USA case, since their army is designed both to invade and defend, their commandos / crack troops will be the first to die since they need to infiltrate into enemy's base.
in SG case, since our army has never been meant to invade or conquer any countries, our infantry will be the 1st to go and die.
this is because our army is more like guarding the country waiting for enemy to come. when enemy come, all we can do is to send infantry to drive them back.
in such cases, our crack troops won't have much use, unless you're like, planning to send them overseas to crack into enemy's base, which is a death sentence, obviously.
