In WW1 that would be the easiest way to go, more likely he'd stay in a trench for a month and die from any of the magnificent diseases that were around or lose his foot to the mud and be shipped back to USA and starve to death on the streets as a war-cripple.
I like the implication that he'd survive both wars instead of getting immediately domed the second he pokes his head out of the trench.

Epic!
I'll take that over disease or being buried alive in the mud in those trenches.
