The basic problem with the DD figures is that most are in wool uniforms with M1938 field jackets and leggings. The US Army went to Korea in HBT fatigues and used the later M1943 uniforms (and their descendants) for cooler weather. The BBA - series figures are generally OK because the Army and Marines used WW2 style coats, etc. for winter (although later issue items were there too). There were few tanker jackets seen in Korean photos, although the armor crews did have some still available.
Interestingly, the Iwo Jima Marines can be used for Korea in the warm weather. I don't know if they changed the leggings to combat boots by Korea, but the rest of the uniform didn't really change.
The Chaffee is basically good for Korea in either version. They were found wanting against the T34/85 but stayed in service for patrolling and anti-guerilla use. The other closest K&C tank for Korea was the old DD27 Sherman as Andy captured a lot of late features (not perfect, but useable). The Army also still used the GMC CCKW truck (DD40 I think) and the M16 AA halftrack (DD35) in Korea.
