Military slang has been around since there was a military not suddenly beginning in or during veitnam. While I'm sure there are period specific slang; e.g Vietnam, Korea, WWII, etc, no one War can claim to have started it in whole. Slang morphs with the soldier and equipment used over time.
Just facts.
" balls to the wall", as a prime example, originated during WWII with bomber pilots. It refers to the power lever settings that had "balls" at the tops and, pushing that power all the way up, was "the wall"; i.e. max power or " balls to the wall".
