I remember my dad (ex Scots Guards), who had three tattoos on his arms always regretted them and advised me never to get myself tattooed. I took his advice. Sounds like the retired AVM referred to by whenurhappy made a wise move getting rid of his.
As for that guards WO pictured, I concede you don't get to a position like that without being a seriously good soldier. Doesn't prevent me thinking he looks bloody awful in shirt sleeve order!
