Korean War Co. B 1st Amphibian Tractor Battalion Tag

[muddyboots]

I picked this tag up the other day. What I have found so far is he was in Korea from December 1951 to September 1952. He could have been in Korea in November of 51 but the records are hard too read. I still got to read where they were but Im suspecting the Pusan are. After Korea he was shifted to the 2nd Tank Battalion and then the 2nd Amphibian Tractor Battalion each of the 2nd Marine Division. On one of the 2nd Tank Battalion Muster Rolls there is a K written by hand by his service number as with other Marines but not all and no footnotes or maybe Im not understanding it. These Muster Roll are way different than WW2. Any help would be greatly appreciated.
