All aspiring Sappers... Aesop081 said it very well - it is the best the Army has to offer. He and I soldiered together for 11yrs, almost all of it in 2CER Petawawa. We've both seen our fair share of Reserves come through the doors. It is a very rewarding trade, where you will use both technical and tactical skills.
When I was in 3Fd Sqn (reserves in Ottawa) I used to love going back into school or work on Monday, listening to what everybody else did over the weekend.... went camping, drank some beer etc.... when my turn came and they'd ask me what I did.... Well let's see - blew up an old tank and cratered a road with 100kg of explosives!
Join the trade, get your training done soonest, put up with the crap on course and get to your unit - you'll love the job.
Chimo!
