"Look at all the things those 4 man, no weapon rack access squads can do! Why can't my 5 man, 3 slot, cooked frag, tiny target size squad do those things!?!!? "
falls: camo, airdrop, bundlenade, smoke, faust, field upgradeable weapon slot with no need for tech, etc,
Obers: ability to upgrade for either long range or short range combat, bundle nade, smoke, booby trap, etc.
Pgrens: viable vanilla, can be upgraded with G34s, be used as powerful AT unit, camo, bundle nade, satchel, reps, etc.

Rangers are basically: you put Thompsons on them, you run them into CC, that's it. It's quite similar to how Rifles are used most of the time. 3xBAR is pointless, Zook Rangers are pretty pointless. The Ranger nade is quite anemic. All those German elite units get useful utility or ability to change/enhance tactics.
