Just some advice from me, take it or leave it.
1. You probably should talk to someone lower in rank than your CO. He might not know who you are, why you are asking him "what can I do this summer?" or be busy with say, oh, running his/her unit on the little time a Reserve CO has to do so. If the RSM is standing there when/if you DO attempt to query the CO directly, he may wish to talk to you after. The RSM, realizing you are an untrained Pte, may then wish to talk to say, your Crse WO, or Section Commander, in a way that your Crse WO or Sect Cmdr may not really like.
2. If you are on SQ now, or BMQ, or in a Section (somehow), then...your Chain of Command would be found there. I am thinking they might, if they know, tell you when you BIQ would be running. Until you complete BIQ, you are untrained as an Inf soldier in the Inf MOC.
3. RSM clerk is probably not a CF trade. RMS Clerk, however, is. They will probably, particularly the Unit Chief Clerk, called the Chief Clerk, be the person to talk to about this either. See comment #2.
4. A unit "dispersing" for the holidays is usually referred to as "stood-down" or "on leave". FYI.
