 Memorial Day is a day to honor service members who gave their lives in defense of our nation, its values, our freedoms, and our liberties. Service members like Sergeant William W. Say and Specialist 4th Class Larry G. Dahl, who were assigned to the First Logistical Command, which is today known as the First Theater Sustainment Command. Dahl saved the lives of members of a gun truck crew while sacrificing his own after throwing himself directly onto an enemy grenade. Say, served as a driver on a resupply mission, he was mortally wounded by a sniper's bullet after engaging the enemy, saving the lives of fellow soldiers during an ambush. For their actions during the Vietnam War, they were posthumously awarded the Medal of Honor. This Memorial Day helped us salute the more than 1 million Americans who gave their lives to defend our country.
