Ask Christmas and Babycat

[G$$]

I don't get this. Is it the perception that soldiers or military people are dumb?

It's not my perception, but it's a portayal that has been used in a quite a lot of comedy. Of all the examples this is truthfully not an oxymoron but is commonly treated as such.

Insinuating :
indirectly, suspiciously, say/ write something but in its negative way

not saying it's wrong but where are you getting your definitions from?
