No problem, your welcome brother. My son was 0321 and did a lateral shift to 0372 a few years back. He has had to explain all of this to me like 4 times... I was confused about it all as well for a while and thought 0372 was rockin the HK's but they are not... Weird, but its the military, who is run by the USG so it really shouldnt suprise me. Hahahaha...
