On the one game I played, where the third UFO I saw was a harvester, I sent my second team to go deal with it and it happen to be in a desert in the middle of the Amazon (You be surprised by how often that happens). So I wound up with a rookie team in a long range fight with no cover. I kept trying to get everyone in the rescue zone I ended up getting six of eight in because the last two guys were doing the best. I ended up with everyone but three guys critically injured and in the turn I finally got the guys in the drop ship an alien with a plasma rifle managed to get at that angle where he could see everyone and promptly went full auto on number 8 who was, of course, standing in the back so exactly this sort of this wouldn't happen. In the end I managed to win the battle with no loses by getting lucky and most of the aliens spawned inside the UFO so I was able to get my soldier with the grenade launcher close enough to shoot at them. I swear the grenade launcher has to be one of, if not the, best weapons in the game.
