1. We do field training, not "infantry" stuff. You'll do a 5 day confirmation exercise on your Apprentice course.
2. Your time in the reserves will determine whether you get a recruit school bypass, which allows you to keep your BMQ and SQ. If you've only been in a year, you may have to do it again.
Search around the site for "CT", "recruit school bypass", and you should find some good information.
