Rubbish. Explorers are jetpacked goody hut poppers/enemy locators/city site finders. I Love Em Warriors are Great for cheap marshal law, and eventual 10 shield cost riflemen, cheap expendable psuedo explorers. Marines seem to fare better than Alpine troops, if I need the movement of alpine I build them, otherwise I'll go Marine. Helicoptors are pretty bad come to think of it> if they get attacked, they die, period. They cost way too much for that ability.
