Hi I'm new here (although I saw another guy named Cool Hand, in 2 words, whereas I'm Coolhand).
Your topic sounds like the one I've been looking for. I think the units you are talking about are Ebud's Ghost Recon units (partly based on UCE eastern units, with help from SelectThis and Tigershark). I really enjoyed them in 1.46 and now that I have 1.85 I wanted to modify the units to carry handguns. I modified Scott Ibrahim's PBO file to add a gun but... even though I can fire it, it is invisible.
If anyone knows a way to fix this problem, I would also apreciate being able to use handguns with some of my favorite units... That makes 2 of us I guess ;D
