Red Shirt Fridays show that you Support Our Troops. RED stands for Remember Everyone Deployed. There are 160,000 men and women in our armed services who are deployed somewhere in the world. 1/3 of the Navy service members are deployed at any time. Red shirts are available at VFW4031.org or at VFW Post 4031. Red Shirt Fridays are particularly pertinent during May during which Memorial Day is celebrated.
