The latest issue of this magazine (by far my favourite, has gear, tactics, techniques and such in it, as opposed to Soldier of Fortune or SWAT........ which I tend to buy a fair bit as well, but sometimes won't due to lacklustre a issue that doesn't make me want to spend the $6.99).
The article, Reality Based Training Saves Lives, spends most of it's time (on the gear side of things) going over airsoft, and they focus on the Systema PTW (Professional Training Weapon), which in itself is a VERY sweet setup!!! As close to the real deal that airsoft can get.
