Men in short skirts?

Are these fellows in skirts? Or are they in shorts? Or even, if you look closely enough skorts?
Interesting way to toughen up a bunch of blokes - by changing the way they dress by putting them into dresses. By no means is dress wearing not tough - hell 50% of the population tend to be wearers of non-trousers and it would be foolish to think that they are anything but tough. Perhaps it's a tough-guy thing about being tough that being transitioned into a non-trouser situtation might be seen as something less than optimal. Still there they are. Acting as one and having something made of them. Looks like hard work though, skirts or no skirts.
