My XVIII Airborne Corps Handbook Circa 1992 Says:
And we did it too. Guys going to SFAS and other schools often did a double (24 miles within 6 hours). That is because you needed to do 24/6 to pass SFAS back then. I think it is the same today.12 Miles road march with 35 pound rucksack, LCE, Kevlar and individual weapon within 3 hours. This must be completed as a unit.
By 1999 it read:
I do recall that prior to that time some units would conduct marches in PT gear and boots. That was pretty lame. The increase was inrecognition that not everyone was in the infantry. Infantry units (and others) kept the 12/3.Annual 20km (12.5 mile) road march < 4 hours (with 15 to 72 lb. rucksack, Kevlar, individual weapon, BDUs and boots).
Minimum standard. Often done faster.
In 2010 it read:
I believe the 82d Standard is still 12 miles within 3 hours with full kit. Anyone with some source documents feel free to correct me.Running and Foot Marches on Roadways.
One of the greatest dangers on Fort Bragg is Soldiers conducting foot marches during hours of limited visibility. Preventive measures must be taken to ensure the safety of everyone involved in these events. FB Reg. 385-10 lists the measures that must occur when Soldiers are running or marching on roadways.
Composite risk assessment (DA Form 7566) work sheets will be completed on all foot marches
and large formation runs and be reviewed at the unit’s next higher level.
The reason for the 12 miles in three hours is because that is the minimum standard for the EIB. The road march is considered the easiest part of the EIB. It is done with 72lbs of pack and gear. It is done last after most have already walked at least 30 miles in the previous 24 hours doing day and night and nav and other tasks. Recently (this year) they added a weapons proficiency task after the march. This means you have to be able to fight at the end.
Clearly the idea that these things can't be done is crazy. There is no reason to think that any civilian in good health can't train themselves to similar standards.
