Bill, remember SF and the attempted SPARTAN doctine?
Slapout, help me, I don't recall this doctrine, but then again I didn't read too much doctrine back then

May be fifteen if they're really doing welll.
Ken, it takes five years to get a concept approved, another 7 to get the funding and manning, so really my buddy's suggestion about every 20 years is probably about right. Completely unfeasible in our bureaucracy, but as LTG Boykin put in his book they had to form Delta because SF was too conventional. I don't think SF was too conventional, but they were rigidly adhering to legacy definitions of unconventional. What was the issue back then that was driving the force change requirements for SOF? Oh yea, terrorist groups from the Middle East, both Palestinian and Iranian sponsored. Amazing how long we can keep our heads buried in the sand.
