Humpin' 

Slang, possibly from the end of World War II, but it was certainly used by the US Army during the Vietnam War. It means a heavy or awkward load in adverse or difficult circumstances.

When they first heard it, the expression “humpin’ the pig” the word humpin' caused a certain amount of consternation among reporters (see humping). The pig in question was not a pink bacon producer or an officer of the law but nickname for the M60 machine gun, so the grunt they were interviewing would have been a machine gunner.
