The soldier won’t be thinking about reporting but he will be a “grain of sand” in the system. If he has a camera on his rifle that he uses to check and shoot around corners or ID the blue, that video data can be stored.
As stated the police have video cameras in their cars these day and one force has a set up that starts audio recording to go with the video to the car over a wireless setup every time the officer steps out of his car to do a stop. What is said as well as what is seen can be gone over. One officer told me it took a little getting used to but the upside is well worth having to watch your language a little. Your behind is covered and the number of people taking pleas has gone up.
