Human/Ape hybrid? And I thought this was the Alternate History site! Try Leicester city centre any day of the week. You'll find quite a few.
On a more on-track note, you're probably talking gene splicing etc for a hybrid, however I do wonder what attributes you'd be trying to add to what. Are we talking about making smarter chimpmen or less smart humanzees?
I think the idea is to add the strength of the chimp to the intelligence of the man. Deliberately making a stupid soldier makes no sense, "subservience" be damned.
