From the comments by one of the readers:
At the 8:48 spot is CPT Tom Roy, Captain (retired Colonel) Roy was on his second tour in RVN assigned to Casper Flight of the 173rd Airborne. His first tour was as a warrant officer in the 170th AHC in the “Buccaneers” gun platoon out of Pleiku in the Central Highlands. Our gun platoon, call sign “Cobras”,of the 129th AHC (wasn’t mentioned in the video) assumed duties of gun support shared with our sister company gun platoon “Star Blazers,” of the 61st AHC, after the 335th AHC stood down. Tom was then Assistant Platoon Leader for the Casper Flight which was the 173rd Airborne’s organic Huey and Loach support aviation company. When they stood down, CPT Roy, who had too little second tour time in country to DEROS, came down to our company and joined our gun platoon, immediately becoming an aircraft commander fire team leader due to his previous experience. I had the privilege of flying Tom’s wing for the remaining 8 or so months of our respective tours. Tom picked up the individual callsign “Regent” because he was the finest Charlie/Mike Model gun pilot in country. Cobra Regent and Cobra Alemaster frequently flew as a light fire team. Regent was the most aggressive Lead I knew and was constantly trying to sniff out trouble. Despite his aggressiveness, I always believed that my crew and I would survive when flying his wing because he was just so damn good. What little success I had as a gun pilot and later in my Army career, I directly attribute to (then) CPT Tom “Cobra Regent” Roy.
