When WE used to train for a land battle in Germany facing the Russkies (this was the early 1980's) we always called them OPFOR (Opposing Forces). But funny, all the bad guy uniforms and equipment just happened to match WARSAW Pact stuff. What a coincidence!
I guess we have never been too subtle about it.
Kinda like at the beginning or end of some movie when they say in the credits something like "any characters or situations resembling real ones are purely coincidental and totally fictional".
Right.
