1. A dispense mechanism for dispensing a payload, comprising:
an expulsion charge assembly located toward a forward end, and including:
a container that contains an ignitable expulsion charge; and
a fuze that ignites the expulsion charge;
a payload section that contains the payload;
a pusher plate disposed in proximity to the expulsion charge assembly;
a tail assembly that is secured in a detachable manner to a rearward base section of the payload section by means of an attachment mechanism;
wherein after ignition of the expulsion charge by means of the fuze, resulting expulsion gas forces are generated and cause the pusher plate to act as a piston for transmitting the expulsion gas forces through the payload section, to the tail assembly; and
wherein the expulsion gas forces continue to increase until the expulsion gas forces acting against the pusher plate and transmitted through the payload section, to the tail assembly, shear the attachment mechanism of the rearward base section of the payload section to the tail assembly, causing the payload to be dispensed.
