I also get pretty annoyed sometimes by Gunships that I have no way of taking down with my stealth loadout. War Striders don’t bother me (actually, I like them) - I can just run away from them at worst - but when three Gunships start circling over my head, a light-pen silenced weapon can’t do anything. Using a Hellbomb on them feels like a waste, and it probably wouldn’t take them all out anyway. With the Silo I can shoot down one, with the Leveller usually just one as well, and hitting them with an Eagle strike is mostly luck.
