America's Galactic Foreign Legion - Book 4: Demilitarized Zone

Decorated Legion war hero Captain Joey Czerinski and his platoon go to planet New Colorado’s New Gobi Desert to guard the demilitarized zone dividing human-occupied territory from areas claimed by the Arthropodan Empire. With a new alien spider commander, a human boy rising to lead a militia, and McDonald's, Walmart, and Chupacabra added to the mix, the funny bone gets smacked hard.
