Back in the 1970s, I remember a billboard right off of Fort Meade. It showed a soldier in Class A's standing in front of the Eiffel Tower, with the caption "Join the People Who Have Joined the Army."
Better yet, remember the t-shirts they used to sell at the PX: "Join the Army, travel to exotic countries, meet interesting people. Then kill them." or one of my all time favorites: "Nuke 'em 'til they glow, then shoot them in the dark"
