Just wanted to add that I finally managed to clear this in a second playthrough. But I don't think it can be done without using a questionable amount of bandages (I used around 10).
Iron swords, throwing axes, and Iron Helm + Leather Armor were all very helpful.
Also rush the pyro before he can attack you, and the sniper can backstab armored units for 25+ dmg, so if you're going to fight him in a bad spot, run.
