Basically, the Army has codified that everybody has to be able to do everything. Leaders and Commanders must train their Soldiers to do it all, but assume risk in the things they cannot train on (is that a paradox?).

(I did like that video games are now a doctrinal means of training. I self-developed with a lot of "Halo" as a cadet, which is now within the regs.)

That said, this FM serves as a good introduction to training, especially for new company grade officers or junior NCO's, but does not really explain how we will accomplish a T in everything. It is what to do, not how.
