Please don't let this degenerate into a 'whose better at the job' nob waving fest. Ireland/Bosnia are sooo last war! Agreed, it may well happen. However when the booties find that it can only just wobble airborne with half a navs lunchbox post marinisation they will drop it like a stone and utilise the chinook to get their boots on the ground anyway.
Post blade spread and tail fold fit, it will struggle with the booties gun underslung, big style, esp if the conflict is further inland. And if it can lift the gun, then it will have to return for the gun crew. The RN and the booties will finally then see the enormous penny falling from the sky...............which will hopefully sink that deathtrap known as Ocean!
