does anybody use this gun aiming techinque, has it got a name

Good points here(no pun) har har But in the mid 90s I managed to make the cut and I ended up on a twelve man SF team in the US Army and we spent alot of time at the range(s) and it was pounded in to always shoot with both eyes open for tactical reasons which makes sense. It worked okay for me with pistols but with rifles I couldn't help but to close one eye slightly once in a while when I aimed. Must go back those old bb gun days.
