I really can't argue with any of the 'Go Military' posters as at your age it would be the best career move.
But should you not succeed and decide to throw vast quantities of your and other peoples money at aviation would like to argue that a helicopter licence isn't more than a fixed wing one. It is a common mistake that many make.
Yes, it is more to fly a helicopter per hour than a comparable airplane but the Commercial licence for helicopters is issued with less flight hours than airplanes. So as a result they both cost about the same. OK you may only have a VFR Commercial helicopter licence against an IFR fixed wing one. But you are equally employable after completing your licence.
Looking at one of the large UK schools that have Helicopters and Airplanes the cost of the Integrated Commercial licences are 41,125 against 47,235. A rather large win in favour of Helicopters.
Which once you start getting paid a salary will be quickly eaten into as fixed wing pilots do seem to get paid more
