Hey Jane I'm ED Tech and so is my wife. I'm in the Reserves CT'ing to Reg. Force and its taken three years so far for my application to go through. However, seeing as I've been offered a go at the RCMP and have accepted, now I hear back from the CF I'll have my offer by the end of this month. So we'll see if they follow through.
Being a bit partial here because its my trade, I think its a fantastic trade with a lot of opportunities. My wife got in within two months of applying, and she had no electrical training what so ever (ahem it took me quite a bit longer, go figure!).
I can offer you a few pointers if you do switch, but don't be offended please, its just from my own experience that I tell you this.
I was Army for about 10 yrs then CT'd to Air Force and never looked back (not a slag at Army, I loved my time there) because I received a LOT more trades related training and experience than I ever did before joining Air. If you stick with Army its a tri-trade anyways, meaning you can be posted to any base, regardless of Element. If you want more experience on the electrical side I would try keeping away from being posted to a Construction unit because I found I did very little wiring or electrical work of any sort. I'm sure others have had different experiences, but that was my experience. Regular force ED Techs I spoke with have had similar experiences though.
So I've been waiting on pins and needles for the offer come in. I'd much rather join the blues than the reds!
