Final answer:
The DOD policy generally does not allow the awarding of campaign or service medals to foreign military personnel, with the exception of the Congressional Medal of Honor, which has been awarded to notable figures like Guy Gabaldòn. DADT, a separate policy, which barred openly homosexual individuals from military service, was in effect from 1993 until it was deemed unconstitutional in 2011.
Step-by-step explanation:
The Department of Defense (DOD) policy commonly does not grant campaign or service medals to foreign military personnel, with the exception of the Congressional Medal of Honor. This prestigious medal has been awarded to members of various racial minorities, including Mexican Americans, for their heroism during battles such as World War II. Despite the policy against awarding U.S. military honors to foreign personnel, the heroism demonstrated by these individuals, like Guy Gabaldòn during the battle for Saipan, cannot be overlooked. Gabaldòn's exceptional feats were eventually recognized with the Navy Cross and the Silver Star, following public demand after the success of a movie based on his actions.
The policy of not awarding campaign or service medals to foreign military personnel is unrelated to the Don't Ask Don't Tell (DADT) policy, which was a Department of Defense policy concerning the service of homosexuals in the US military. This policy prohibited military members from inquiring about a service member's gender orientation and allowed service by homosexuals who did not disclose their orientation. The enforcement of DADT was barred by a federal court ruling in July 2011. The evolution of military policies reflects ongoing changes in societal values and legal standards over time.
