If this was the tool at KAF, thank you for writing it! (a friend of mine was a CF doctor there, and I spent some time in radiology getting the US PACS stuff integrated with the Canadian stuff)
I know it was used at TFK for I was there and originally, at that time, we were the only unit operating around KAF (aside from the defence team of KAF itself). Later our area of operation got split in half and shared with TF Striker, a US mechanized brigade. I shared my tool with them and I know my counterpart in their brigade HQ used them, but I don't know for how long as I left a little later.
For a period between April 2010 and Sept 2010 (maybe going later than that), all of TFK's MEDEVAC, which must have accounted for over 70% of MEDEVACs in KAF, were fulfilled using this tool.
