Altered_Soul your such a dick dude -----RED 2 RULES
To know dickery one must be a dick himself. RED 2 4 LIEF!
Ahem, excuse me: Boltaction, thats a good attitude to realise it, but try and get out in games before to get an idea, develop an interest in gear, and match the unit you choose when registration opens up. Learn basic unit communication, and basically use the Combat Challenge website stuff as a guideline (it helped me). Play some "smaller" ops, there is plenty of time in the way. Also, the age thing I am not going to lecture on, but work that out with the organizers and see what can be done (if anything).
Also, learn to run as fast as you can from fast moving, heavily armed vehicles. And to plan a perfect ambush only to kill your own team's commandeered transport. Go Red 2!
