C.O.D!!!!
Congratulation on joining the best trade in the Army!!
Yes you will deploy! Yes you will love it! Yes you will make a good buck doing it!
Day to day life? Like so many things, you get out of it what you put in, but I'm sure you're looking for more detail. While there is a long list of duties and a wide variety of taskings you can find yourself employed in, for now, focus on learning what you are taught, increasing your cardio, and talk to every Sig within the sound of your voice. There is so much to learn, and as you learn, you will be able to steer your career toward your preffered direction.
Like anything in life involving people you will meet those who are on their way up, those who are on their way out and some who have gotten stuck in a rut or lost sight of their goals. Learn from their example, you will learn the pitfalls very quickly. Drugs, poor attitude, and laziness can freeze your career and rob you of opportunity very quickly. Remember that while you are in the Army you are always being assessed. The best advice I ever received was from a Warrant Officer Lambrock while I was in Meaford.
He said "Do what you are supposed to be doing, when no one is looking. Your career in the CF is based on trust. The higher you go, the fewer people there are looking over your shoulder, but the greater the fall if you betray that trust."
In our trade I have friends who work on computer servers and little else, their tours are spent in air conditioned offices resolving all manner of computer (and user) issues. Others have been employed as Riflemen. These fired up souls fullfill their Sig duties of making sure all comms are good (don't worry you'll find out what all that entails later), and then continue on as if they were infanteers. These guys eat, sleep and breathe right along side the infantry guys.
Every few years in the Army you will be "posted", meaning your job will change, as a Sig, this means you have the opportunity to work with many different trades over the course of your career. I have already worked with Supply, Infantry, Armoured, vehicle techs and more
There will be times when you have the opportunity to choose what you do, and there will be times when you will "choose" to follow orders regardless of your preference. The best thing you can do for yourself at this time is increase your physical fitness and foster a strong mental attitude. You are embarking on a career that will test you mentally and physically, and as you will learn, the greater the challenge, the greater the sense of accomplishment!
Welcome to the family, you will love it!!
