People always ask me what they can be doing at this point in the game. I always respond with "training", and not just firearms and tactics training. The understanding and implementation of real-world intelligence skills is arguably every bit as important as the "hard skills" and probably more so for a large segment of the community; in other words, everyone can be playing a part in the "Great Game" (as Kipling put it), but not everyone can be running and gunning, so to speak.
As someone who spent a large portion of their military career engaged in reconnaissance and the "collecting" aspect of intelligence, it was good to spend some time in the S2 (Intel shop) shoes. There is a lot that goes into creating actionable intelligence and Sam's course does an excellent job in covering the necessary skills in a short amount of time.
I would encourage everyone to make the time to attend his course. It will be time well spent.
