I may get shot to bits here, but just ignore the commitment and don't leave a forwarding address. You go onto the reserve list so that if the balloon ever went up they could have a go a calling up ex-servicemen and women. You don't go anywhere, you don't do anything, you don't keep anything. Not sure where you got your pitchfork, but they haven't been authorized issue for years and should have been returned to stores. I wouldn't go around shouting that you've still got yours.
Remember, if they can't find you, they can't recall you!
When they call you up, good luck with the CDT.
