Which service is he in? Maybe find a panel with their emblem and use it in the center of the quilt.
I like the idea of flying geese flying around the emblem.
Or a star pattern. You could make the center square and the star points our of camie and use black for background.
Different services have different colors for their dress uniforms. Army - dark green with a light green shirt. Navy - dark blue or black with a white shirt. Air Force is a medium dark blue with a light blue shirt. Marines have the dark blue with the red stripe on the pants.
I googled military quilts for ideas:
