Smoke Grenades makes it so Turrets can't lock on to you
HE Grenades usually 1 shot most mechs / tiurrets
Rockets will definitely 1 shot if you hit them head on
Big guns with AP ammo can deal with them
EMP grenades, Emp ammo will just decimate them
Big Melee Pawns with Big hammers can also lock them into combat and deal with them quick

Basically all revolves around you actually investing into your weapon tech to get the tools to deal with them effectively. It's not like Vanilla where mechs are just like any raid except they are tanky and don't flee. The game warns you mechs are coming for a reason.

You should also install Grenade Variety for CE
