Lol, and just to sweeten the confusing ninjasniper pot, here is LtCol Bernd Horn's defintions from this article, worth the read (http://www.journal.forces.gc.ca/engraph/Vol5/no3/Special_e.asp)
Seems to me that we have to get General Hillier to sit down and write up an instruction manual on this stuff.... :blotto:
- 'Tier One' SOF consists of primarily 'black operations' or counter terrorism. Normally, only 10 to 15 percent of those attempting selection are successful. What makes this number so impressive is that a large percentage of those trying out are already second or third tier SOF members. Organizations that fall into this category include the US 1st Special Forces Operational Detachment (Delta), the German Grenzschutzgruppe-9 (GSG 9), the Canadian Joint Task Force-2 (JTF 2), and the Polish Commandos (Grupa Reagowania Operacyjno Mobilnego) (GROM) (Operational Mobile Response Group), to name but a few.
- 'Tier Two' SOF reflects those organizations that have a selection pass rate of between 20 and 30 percent. They are normally entrusted with high value tasks such as Strategic Reconnaissance and Unconventional Warfare. It is at this level that selection is separated from training because the skill sets are considered so difficult that the testers are looking only for attributes that cannot be inculcated. The actual skills required can be taught later during the training phase. Some examples include the American Special Forces (also referred to as Green Berets), the US Navy SEALs, and the British, Australian and New Zealand SAS.
- 'Tier Three', consists of those units, such as the American Rangers, that have a selection success rate of 40 to 45 percent, and whose primary mission is Direct Action. At this level, selection is mixed with training. However, the quality control line is drawn here. Generally, units below this line are not considered SOF.
