Interesting recruits video from the US – all done in the name of fun! Umpteen casualties in the tower on various levels so requires quite a few ladders.
But just take a look at the 9m ladder. Three man pitch and, unlike ourselves, there's not three rounds above the sill. Now take a look at the foot of the ladder – no one is footing the ladder for more than a few seconds at a time. And right near the end of the clip you can see there are now two people on this unfooted ladder.
That's a training need if ever I saw one!
