A great explanation from Michael C that makes me wonder if the fact that the Marines were CSTC-A ETTs not under ISAF may have inadvertently caused some problems with respect to mission planning and QRF coordination. I do not know how things are in RC-East but in RC-South I saw some coordination issues between OEF CSTC-A and ISAF coalition forces (exacerbated by the fact that coalition units did not have Blue Force Tracker).
