Thanks Boffin, I think I'll have to read in on that, though it made more sense when I reread it as recuperating, rather than reciprocating, which I did the first time round!
I thought one of the Falklands' lessons learned (but obviously not heeded) was that a single barrel gun is not good, hence the Paras' lack of NGS at Goose Green when whichever ship it was allocated to support had a lengthy stoppage/jam? Would it be that much harder to have a twin-barrel turret?
