Both UV and the BM episode strongly reminded me of an Outer Limits (I think?) episode about a perpetual war between humans and aliens in some underground cave. The reveal is pretty similar to that in Men Against Fire, except the justification is different.

Haven't seen either of these yet, but the way you're describing them it sounds very reminiscent of Ender's Game too.

Yes, that's the one. Thanks for looking that up.
