When I flew with the Mafia, once a month, squad night, we would go over thinks players had questions on.... how to dive bomb in a 38 with out lawndarting and such.
When I flew with the Ronin, odd would setup nights for training, some with the trainers, and we would go over things, but it wasnt some weekly, by weekly type thing. Odd would ask, if there was enough intrest he'd set it up.
Now I fly with the 56th. We dont do "training", but the top guys are willing to drop what ever they are doing to do some work on one thing or another. I have been lucky to have squad mates that are willing to train others. Most are very humble and start out with "I'm no pro, but...." but then get down to business.
Todays player I think is more of a gamer, and they game. That is their practice. Squads are just "clans" or "facebook groups" to most of them. In the old days I think more players took pride in which squad they were in and wished to work at getting better to NOT let the squad down.
