Complain? Tank commanders job is the best job you will ever have....who needs pay! It's the biz. However if you are a tank commander, L/Cpl / Cpl / Sgt. Just enjoy the moment.... the pay is secondary. Then again I'm just a romantic! But I loved every minute of it!
ps: Just wait until you get to be Troop Leader....I'd pay MOD just to do that agin for another year , as a Staff Sgt.!!!
