It's TACP weekend on Grey Ghost Gear's Facebook page.
JTACs and ROMADs can post a picture of themselves after liking the GGG page, tag the GGG page, and be entered to win free kit (GGG recently sponsored the TACP Association Reunion). Looks like it may be for Coalition FACs, because there's a British Army JTAC in there too.
Great article on JTACs from Michael Yon: http://www.michaelyon-online.com/jtac-joint-terminal-attack-controller.htm
