On Memorial Day, the United States Postal Service will honor members of the military who gave their lives serving our country.

The USPS will issue postage stamps featuring four Service Cross Medals -- the Distinguished Service Cross, the Navy Cross, the Air Force Cross and the Coast Guard Cross.

A dedication will be held at 8 a.m. Monday at the World Stamp Show NY-2016. 

The Service Cross Medals are the second-highest military decoration for valor in combat, after the Medal of Honor.
