Pretty much all been said but don't forget the opportunities for Adventurous Training and the like. Despite what people might say or think they are still there. If you are prepared to seek out these opportunities you can expect duty status for skiing, gliding, parachuting etc. and most sports.
This year I went from ski slope to sand storm within a few weeks. You can't beat the variety of jobs available and I personally appreciate the extra duties that give you something different to do other than controlling. If you join as an officer you will be expected to lead others and develop you management skills from an early stage. RAF (war fighter is the buzz word) first, controller second.
Go for the RAF option if you want the "service life" with ATC on top. You can always think about going civvy later in life.
As for the air to air refuelling I ended up learning the task, normally left to Area Radar types, whilst controlling in a well known location in southern Iraq. A short notice tactical towline was set up, the jets needed "snappy vectors" and I had to get the "chicks" to the "mother" very quickly as they were fuel critical. Luckily I had some ex Area types around to advise me. A great feeling to know you have helped out in real time operation. Was also de-conflicting with other jets in the area and civil aircraft. Quite a busy period but very rewarding.
Best of luck
