The U.S. military has a strong trademark portfolio. A few of the trademarks owned by the Marines, Army, and Navy include:
A FEW GOOD MEN
HEAD FOR THE FUTURE
BE A FORCE
NEVER STOP ADVANCING
Using the military’s protected federal marks is a sure way to find yourself in federal court. They also don’t seem too amused with parodies of their marks. A colleague said it best: “Pick your own battles.”
By the way, to the armed forces, these are both big money and a reputation to protect. They will fight to the death.
