For those newer members, the "super-regiment" has been discussed quite a few times of this board, I'd encourage you to search for the threads as they were quite interesting. At any rate, a bit of history: In 1804, the British Gov't contemplated doing away with the kilt as a uniform for Scottish troops, causing an uproar. Col. Alan Cameron (79th Cameron Highlanders) defended the kilt thus:
"[the kilt has] free congenial circulation of pure wholesome air (as an exhilirating native bracer) which has hitherto so peculiarly benefitted the Highlander for activity, and all the other necessary qualities of a soldier, whether for hardship upon scanty fare, readiness in accoutring, or making forced marches &c., beside the advantage, when halted, of drenching his kilt in the next brook as well as washing his limbs, and drying both, as it were, by constant fanning, without injury to either, but on the contrary feeling clean and comfortable..."
My favorite quote from his plea:
"I sincerely hope His Royal Highness will never acquiesce in so painful and degrading an idea...as to strip us of our native garb...and stuff us in breeches!"
...A little history for inquiring minds.
