Some interesting links on 'carrier' shells (the ones that disperse leaflets):
http://ww2propaganda.eu/spread5.htm
http://www.psywar.org/105mm.php
So apparently a 105mm shell could hold 500 leaflets of the 4.5" x 7" size. It also seems easy to load "when needed" rather than requiring the leaflets to be pre-loaded. So: the team gets X number of empty carrier shells, and Y number of stacks of various leaflets.
