I recognize the cat is the Capitol Division. Wondering if anyone knows what the other two are? I realize the LSI may not even be Korean, they just all came together in the same kind of bags. Any help much appreciated!

Thanks, Jon.

LSI was a US civilian contractor in South Vietnam.

Thanks Beezman!

LSI would have been training Koreans:

 

"Initially established to meet the aviation training and support needs of foreign militaries operating U.S. Navy aircraft and systems, LSI has developed an enviable reputation for innovation, responsiveness, and reliability among a customer base that includes the U.S. Department of Defense, Department of Homeland Security, numerous foreign militaries, and the largest defense companies in the world."
