Just brainstorming and there was a feature which was implemented in Rebelstar which I haven't see in other, later versions. The idea that moving into certain terrain features gave protection. Maybe too cumbersome for xcom which doesn't have a similar feature. Not sure if this was implemented in lasersquad, doubt it. But just a thought.
What about some single man pillbox or ... a telephone booth? Maybe you can hide in a refridgerator and survive a blast or get ignored by a chryssalid?
Or maybe its a feature that the aliens can use?...
On that matter, how about coffee machines and lawnmowers?....
