A couple people bought personal optics when i was in a-stan, like me. Because well, the CCO sucks. Someone in my company bought a tan one. So there, thats at least one person who was in country who bought one.
I took mine off. Served no purpose really in a-stan for me, all my engagements were at 250 meters+. Also, i really didn't want to take the extra time to zero the doc. Yeah like danger dan said. I had the model in black but was identical to the tan one. Really no difference at all. But, the one i had had a different reticle and range markings compared to the issued ACOG RCO.
