I refuse to use the term tartan army. When people use that term they think of big hairy, soft, chucther jessies with feathers in their hats.
The scotland fans are made up up many different people such as hairy arsed glasgow hardmen, big tough aberdonian oil riggers, neds from dundee, embarrassing posh arseholes from edinburgh to older minted toffs from the highlands.
You could pick 2 scotland fans out at random and one might be a nutcase from glasgow who has slashed someone that day to a feeble pansie from the highlands that likes to sing about drops of golden sun
The term tartan army is meaningless
