I was at Speicher for OIF IV, and thankfully the pt belt rule had not arrived yet, but we did encounter its introduction at LSAA when my guys were refused access to midnight chow bc they did not have PT belts with their IBA's. (note: we got them into chow)

One of my drivers got a ticket for speeding on the Speicher perimeter road after refueling (if you've driven it, you know). We were more concerned at why MPs were patrolling Speicher and not ASR Hershey, but that was above our level.
