Yeah, with a pump, you have to play "around" the tac squads. You can scout for them, pick up their squirters, or wait for the opposition to come back your way after they finish with the big frontal assault.
It's kind of fun to find a good target for them and watch the gung ho go.
When you play against them, you have to have a lot space with a pump, or just bring something with more umph. Somehow, many of them don't recognize the lessons from the first world war and will charge bunkers they haven't actually located yet. Some won't actually move without a command, and you can slide on up in the brush while they are forming up. Them's good pickin's with an RT.
