I can't figure out how these troops work in this game. They are hybrids that do not seem to do either melee or ranged fighting well. In particular, in melee they keep switching primary and secondary weapons back and forth until they get slaughtered, even when I put them out of fire at will mode. This seems like almost a bug, as I do not have the same problems with non-skirmish missile troops. Has anyone figured out how to employ these effectively?
