I wonder whether specialist teams like snipers or forward observers actually have special properties or whether they differ from the other pixel troops only by owning special equipment (like a sniper rifle or binoculars). For example, are snipers and FOs harder to spot because they are trained to conceal themselves. Or do FOs have a bonus when spotting versus regular troops equipped with binoculars?
I know I could test it myself, but maybe someone already knows the answer.
