Gidday, these vests apprear to be armour carrying types, similar to those made by SORD, or could even be them, with the molle system so as an individual can set his rig up to suit his needs. If you take note, the basic vest is the same, but not the lay out of the pouches ect. I am ex military and have one very similar.
These guys are from Task Force Black and they wore a multitude of different uniforms and equipment set ups. These dudes are NOT Airsofters, thats for sure, they are the real deal.
As for figures, Maurice Corry did two figures of a Task force black operative, one in 120mm and the other in 200mm, both excellent figures, I have painted the 120mm one up and its very nice, the other is still waiting to be done. Hope this is of some help. Cheers
