Coco, with that minigun of hers needs something of equal rapid fire nature. The McDonnell Douglas Harrier II was introduce to the british armed forces in the cold war, it featured a GAU-12 Equalizer Gattling Cannon, so that seems suitable for her.



Velvet, well this is a bit difficult, while i'm not caught up with season 3 I don't think they've revealed her special weapon yet. That said I'd make her the prop plane, the Lockheed P-38 Lightning, while an American Design, was used extensively by the British forces, and to great effect. it's twin engine twin tail design goes well with Velvet's bunny ears.



Pyrrha should be a tank, no questions asked, with a sword & shield/rifle combination tank seems most appropriate. For her I'd say the Tank, Cruiser, Mk VIII, Cromwell. A quick, and well armed vehicle for its time.



Nora's simple, the HMS King George V, served in both theaters of war, participated in the sinking of the Bismark.
