Light infantry foot mobility standards?

[JMA]

Running 26.2 miles at any pace is an accomplishment -- I've never run farther than 20 miles at a time myself but it was plenty! for me, the difference between 12 and 15 miles isn't so much, but there is definitely a difference between 15 and 18 -- but 4 hours 30 minutes is as you say average. I think the qualifying time for the Boston Marathon is 3 hours 10 minutes.

Twenty-five miles in four hours in kit wouldn't be a superhuman feat but it would require serious athletes, not just a bunch of guys in good shape. Seems like overkill to me, though. Twelve-and-a-half miles in two hours with that load would tell me enough about general fitness. (Or as my high school cross-country coach once told me, "Most world class distance runners aim to run 100 miles a week because it's a nice round number. 88 seems just as round to me." )

Often the original intention behind this training is good... but in peace time the 'means to the end' often becomes the end in itself.

The idea behind these marches is to approach the enemy on foot and surprise them by putting in an attack after the march. For this purpose the Brits use 'march and shoot' exercises where at the end of the (often) ten mile march troops need to shoot for a score.

The idea is for the company/platoon to arrive together in a condition to launch directly into an attack. So the speed is controlled (or should be) and the weight carried should equate to first line ammo plus a reserve (including light mortars) to sustain an attack on arrival with enough spare to fight off any counter attack before reinforcements and/or the land tail arrives.

This is the idea... but you will always find (idiot) officers who turn it into a speed competition leaving the troops in no condition to fight at the end of the march.

As they say... some mothers have them and the army gets them.

Edit: I note I commented much the same earlier in the thread. In fact I would go so far as to recommend that a company commander gets fired/relieved if 6 men (two per platoon) drop out of the march (which must be conducted at a controlled pace). If more than two drop out per platoon you fire the officer and the sergeant.
