Re: WTF ?!!
If the armour is any good, then surely the baton round's energy will deflect across the armour? In which case the felt impact will be not much different to the recoil from the gun (by conservation of momentum). That is, unless baton rounds use propellant to be recoil-less, I don't know. It would feel quite uncomfortable, but better than being shot with a bullet wearing a vest, for example.
Of course, this armour is just for show, so I guess it wouldn't be any good at actually working.
