I've seen the both at Grantham (on both Reg and TA) but also on the WOs course running at JSCSC a couple of years back. Looks toss and they should be charged for a replacement Lightweight combat jacket.
Unless I've been Wah'd, I suppose he's going on about the 'Lightweight Field Jacket' which is what is says on the label inside your shirt.
Agree that it looked good on the old KF, mainly because the massive rolls of woolen material were a right b'stard to iron flat without about a can of starch on each fold. Being a lazy minging cnut back then, I'd go for weeks between washes rather than re-iron the things from scratch until I coughed up and got two tailored.
I've toyed with the idea on CS95, but there's no problem compared with KF.
Also, my Sqn doesn't seem much interested in uniformity of uniform and it seems to be at the whim of the DS whether it's sleeves up or down on any particular day.
