Worth mentioning GUNO, what the sailor did was worthy of COURT MARTIAL. I don't know about all services but the NAVY at the time didn't allow skills/crafts/rates for black sailors in OPERATING GUNS!
"Justice" DELAYED is "JUSTICE" DENIED. MOST of these stories don't have happy endings. The US MILITARY systematically withheld AWARDS and MEDALS from Negroes and JEWS throughout and AFTER the 2nd WW. Depending on the tenacity, guts, relentlessness, resources of the families left behind to go through the 'paperwork/records', letter writings, appeal after appeal and shaming of the services and/or their elected officials, these stories rarely turned out well.
This was a fucking MIRACLE.
