Well I just had a fun LW mission.
So It was Destroy the Alien Relay. There were 18 enemies on the map, mostly advanced mutons, powerful Advent, and MECs. So what I did was bring the heavy weapons class, the technician, but outfitted them for stealth. Since Fire often times destroys the relay with how it destroys the environment, I snuck them to the relay, called EVAC, then set the relay on fire and managed to get out of there with 3 mutons on my butt, being suppressed by a MEC, and I dunno how many advent/Mutons around the building waiting to get a piece.
These are all enemies with 10+ hp, hit for 10+, and have 75 aim mind you. And my soldier had 4 health. Stealth at its finest! though it is weird stealthing with a flamethrower...
