IMHO: It's not worth getting armor on Outpost.
I often survive 1 or 2 hits in the first wave with no armor, but if I have Light armor and Weapon Carrier, a pistol shot from ~100 yards.

The best strategy that has worked the best for me consistently, is to put all supply points into weapons and a light carrier.
I only take Heavy Armor for the seventh(last) wave, if I have the points to spare.
