The C&E site mentions an Academic Bursary, but not much else WRT how the Branch fund dollars are allocated. I would imagine that it would be involved in most of the annual events and similar activities. Also, If I remember correctly, back on my 3's, the Branch fund paid for our first set of accoutrement's for CF's and one set of slip-ons for combats.
I don't know if it would be involved with the Museum or not. I recall having an allotment during the construction and move from the Forde Building, but I think that might have been a separate fund altogether.
