The squad formation and movement video is really handy for helping people understand concepts like 360 degree security, wedge formation and combat spacing. The squad attack video is good for concepts like base of fire and maneuvering a fire team to an enemy flank. A good basic thing to take from the from the videos is the load-out of the different soldiers. In Arma, everyone seems to want to take a DMR or sniper rifle, which is understandable in the long distance engagement of Takistan, but it really helps having an automatic rifleman in each fire team (4 man group), and a machine gunner in the squad (8 man group).

The software used to make these videos should look familiar. VBS2 (virtual battlefield simulation) is the Arma engine, turned into a training tool for various militaries, etc.
