Wilf, could you elaborate your this thought in this thread context.

PBID essentially suggests that you train, organize, and operate light infantry in a way that best utilizes their inherent strengths. In practice, this means that you train infantry to accomplish two basic tasks, these being a reconnaissance patrol and an observation post. These two core skills are built on a high level of individually developed field-craft skills. In simplistic but easily understood terms, you train Soldiers as snipers and then train them as a recce platoon.
Why? Surely this is completely against the teaching that only the brightest, best, and most experienced of infantry unit Soldiers become snipers and members of the recce platoons.

Ken White porposed his definition of sniper:

An individual with an effective long range weapon and sighting appendage designated to fire at high value targets, materiel and personnel with a strong probability of success who is part of the fire support effort.
I think that this is more appropriate to define designated marksman. I'd like to borrow sniper's definition from Mark Spicer's book "Illustrated manual of sniper skills."

Sniping is the employment of individual shooters from concealed positions with no warning, from any distance, depending on the range of the weapon. This is not to say, of course , that to maximize the chances of sniper surviving to fight again, the longer the distance between him and the victim the better. Conversely, if the sniper is able to conceal himself and endage successfully at close range, then that is also sniping.

Last Gun's and Ammo "Book of AR-15" has short article "The Art of the SDM". If understand correctly (with my limited knowledge of English) Army is outsourceing training from civilian shooting community.
