I heard about the new brown shirt. Asked my friend who's a
regular to help me get some so I can look at it he say
"out-of-stock" 
So the brown T-Shirt will replace BOTH the grey T-Shirt+grey
singlet?
Vest slack is an acceptable attaire only while Training [E.g.
Route marches, sia gang
Hmm... You happen to know if there are any new regulations that
come with the new brown shirt, i.e. it can be worn on other
occasions besides training now?
