Ok, back to the resume question. Yes, of course put your Res experience on your resume for a number of reasons, 1) neglecting to include all previous and current employment is considered dishonest if it's found that at a later time you failed to mention that particular employer that is grounds for dismissal; 2) although you can't see right now what being in the reserves has to do with the X position you are applying for, the HR person will see the connection IF you connect the dots. In other words, demonstrate where you have gained valuable skill sets and how you will be able to transfer them over to a new position; 3) use your Res experiences for concrete examples of your skill sets by picking a number of examples from your work/training to use in either your cover letter or interviews.
For example: say the job you are applying for requires experience in team work. Use concrete examples of team work during BMQ to show that you understand what it is and how to apply it. Or it requires you to have good people skills. Use your training sessions at the unit as examples of gaining the experience and citing examples of being able to apply it. And my favourite, demonstrating how you deal with a difficult work colleague or situation. That would be some of you leadership skills coming into play. Give an example of how you used that skill during say a training mod to deal with a stressful situation (I always used the gas hut example).
Draw attention to positive personal traits and use that you had to pass the recruitment screening and security clearances to demonstrate that you are of good character. It's one thing to say in a cover letter, "Oh I am a hard worker", it's another thing to be able to demonstrate to an employer that you actually are a hard worker. I'm sure you can think of a few examples from BMQ that would show an employer that skill.
