"Once per game: Your troops cannot be damaged for the remainder of this round. Then, flip this card. May be played anytime."
Can you use abilities that "defeat" against Aldan troops in the same round that the Camouflage feat is used? (yes)
Some abilities (such as the Ooglan's Parasites and the Ooglan's Eye for an Eye feat) allow for the straight up defeat of troops. Defeating a troop in such a way is not considered damaging a troop. These abilities can therefore still defeat Aldan troops, even when Camouflage is used.
