Larry Vickers is held in very high esteem by many in the firearms instruction field. He's a former Delta Force operator who had many years of just about the most intensive training and experience any Special Forces soldier can get, and then brought all of that to gear development and training in the civilian world. You can read an abbreviated bio here.
Larry - or rather his company, Vickers Tactical - also has a YouTube channel. He's taken to analyzing some of the best-known Hollywood movies involving gunfights and tactics, pointing out the similarities and differences between what they portray and the real world. His commentaries are a very good learning tool for those of us who don't move in high-speed, low-drag circles, such as yours truly.
He's analyzed four movies so far: Heat, John Wick, The Way of the Gun, and Sicario. Click on the preceding links to read about each movie, if you haven't seen it, then click on the links below to go to his video breakdown of each of them.
To whet your appetite, here's the last of the four, Sicario.
I find Larry's commentary interesting as a learning tool, both for what's wrong and what's right in those movies. My military service was in a different war, on a different continent, and anything but Special Forces in orientation, but it's interesting to compare my training and experience to what he describes and portrays. I've learned a lot.
