The blood supply for east Mississippi and west Alabama has been greatly supported by donations from members of the military.
The Meridian Naval Air Station community showed its participation in the cause.
Blood donors wore red T-shirts to form the shape of a drop of blood.
This photo opportunity was done in cities across the country.
"We've been doing blood drives Tuesday through Friday this week, and we've collected over a hundred units of blood in those four days from our personnel here on base," said United Blood Services donor recruitment representative, Katie Swinney. "It means so much to us in our community blood supply. The summer months are so hard for us and NAS has been fantastic with working with us to get blood donors out."
Friday was World Blood Donor Day.
NAS is also competing with other communities to form the largest blood drop.
