CaptainGyro,
Based on my father's comments from WWII, there must be MANY such heroes. = He said that during WWII, putting in a serviceman for a medal (even THE medal) was a really LOW priority because of mission constraints, members who were KIA (and thus unavailable to be questioned about a valorous act) OR simply because in "the fog of war" witnesses disappeared before they could be identified.
yours, sw
