I don't get it!
They are grown men, already!
Don't they already know how to shower? Have they never had a shower before?
So, they have to be taught how to shower?
Unbelievable!
Ummm nothing for nothing, but the point of the shower instruction (Aside from being hot to watch! LOL!) is to teach the soldiers how to clean themselves well and more importantly fast! I don't know about how they do it in the UK but in the American Army the soldiers are trained to be able to take a complete shower in 3 mins. It's all about efficiency. Maybe you need to think a lil more before you post.
