There should be a phone number for the unit clerk or manpower
office. Call them and ask. But be polite - they are not obliged to
tell you over the phone because of opsec issues.
I was an RSAF reservist ( transferred from infantry holding
list) and before my first ICT , I called the S1 and asked. He was
quite friendly and told me approximately what my "new" job would be
but not exactly.
