Canada has different classifications. We do Army, Airforce, Navy, and Sigs.
I was Sigs. It's the best cause one deployment or exercise you can be living gucci on a Navy boat getting three hot squares and sleep, while the next you can be humping it through the mountains with a radio on your back with the army.
I loved the constant change of scenery and experiences.
For those not in the know, the Sigs branch is the radio operators.
I wrote a horror novel, called "Spare Parts." A whole damn novel! You can check it out, and other free short stories at http://www.aarondeck.com
