Recently i got a GoPro helmet cam for holiday -pretty damn cool, got some good footage while scuba diving and bouncing around the sea on a jet ski. I also went to use it on a recent range day - IBSR, CQB and MMTR. IBSR worked well, with again good footage. However, when i went to speak to range officer on cqb range, he advised that if he saw it out again, it would rapidly ascend my ********, which i took to be a no! This in itself is not a problem - there are many good reasons why he did not want one used. On the other two ranges, the RO didnt mind, with the proviso that no military footage goes on Youtube/FB/Cloud etc which i had no intention of doing anyway. When i got home and watched it back, it occurred that the helmet cam could actually be a useful training aid. On the IBSR, there were good examples and bad examples, including those who simply did not understand the concept of a BATTLE SHOOTING range - when the target popped up, they would leisurely aim from the standing position, fire a shot and then carry on. My footage showed good reaction to enemy fire, i dashed, i downed, crawled into cover etc, and then again in reverse when moving on. Useful for a classroom demo? IMO, if a helmet cam is used, it should be with the conditions that any film is technically property of the army and is not to be placed on Social Media or used elsewhere without specific permission from SNCO or officer.
