Thanks for all the links and feedback bros!!

I'm looking into WW1 more than WW2 since the Highland units were pretty much kilted throughout that entire conflict.
I had also checked out some books from the library, and found that the few pics of troops in kilts were few and far between, and most of them were too small to show much detail :-(
A while ago I was moving some stuff around (while kilted) and picked up my bayonetted Mauser bolt-action.
Something hit me while I was there in my kilt, holding the rifle. I could see in my mind's eye with an eerie clarity all those guys my age and younger, cold, wet, covered in mud and probably nervous beyond anything we could comprehend.
In addition to studying their weapons and equipment, you can look at an old photo, see the expressions on their faces, look at where they were and get a vague understanding of how they could cope with their surroundings.
I feel that evertime any of us wear a kilt, we continue the traditions and freedoms that those guys fought and died for.
