This UFO breaching is seriously killing me. Mostly it's because of the way grenade mechanics seem to work. In the original X-COM you had a lot of flexibility with throwing grenades, you could accurately place them at almost any tile. In Xenonauts, it seems like grenades can only be thrown in a "3-point line" arc, which means it will be blocked by the roof.
Breaching in real life is more of an underhanded toss through the door frame, without exposing the body. I can't get a grenade into the craft and hit the aliens without doing some Charles Barkley stuff, which means getting annihilated by reaction fire.
This issue, plus smoke grenades forming a wall that reduces all accuracy to 1%, makes breaching a craft, which is already a disadvantageous situation for the attackers, EXTREMELY costly. It would definitely be easier to shoot rockets at it, but that's not a good strategy for the salvage part of the game.
