Achilles, Greek hero, gay bloke (but the Greeks dont like it mentioned), a bit of a heel.
Achilles, british name for the US M10 tank destroyer (sherman chassis with sloped armour hull and open-topped turret) once the wimpy 3" US spam cannon had been replaced with a properly hard british 17 pounder.
Achilles. Probably the name of a ship (or 7) at some point. The Andrew like gay things and heroes, so how could they resist? Sort of name that could drive a small RN ship to think it was hard and have a go at a Kraut monster of a battleship ... perhaps near Montevideo.
