I havent played impossible yet, but in Classic and below I dont think Ive seen a bomb disposal in the first month ever. I cant say this works on Impossible, but working the edges of the map running in enough to zap a delay device, instead of going through the middle of bomb disposal mission triggers less packs in my experience. If I go through the middle of the map, I always seem to trigger a couple packs with one move. Are the spawn points and packs laid out differently in Impossible compared to Classic?
There might be more mobs in Impossible, I'm not sure since it's been a while since I've played the other difficulties.
Just the fact that the thin men have 6 HP in Impossible means that you can only one shot them with a max damage crit. Plus, their increased aim makes them extremely deadly. Oh yeah, and since your guys only have 4HP, one shot of unavoidable poison could mean death, and possibly a panicked soldier.
