“I once joked with a marine that the only reason we arm our soldiers is to give the enemy a sporting chance.”

I remember the story of a retired marine in the company of fellow retirees on a bus on their way to the Aztec monuments.  The bus was held up by three attackers.  The first ended up dead, the second wounded, the third ran.  Yes, an unarmed marine is still a force.  Honor and thanks are due.
