He does cool exhibition stuff, but very little of it comes across as combat effective to me. For example, I understand that the REEL drill is supposed to mitigate having both team members down during concurrent reloads. However, in the event that I've got multiple targets on the other end, I don't want to be used as a human shield while my teammate sits pretty. I'd rather utilize a firing cadence to ensure that there are two guns in the fight and we're both able to cover each other while reloading. It's worked thus far, so why try to reinvent it?
