Imperial Starfleet Military

The ISM is a large Alliance military organisation designed to supplement the Federation Starfleet with raw military power. In a crisis, Federation officers will take command of an ISM legion and use it to end a threat. The ISM is a separate, but subservient organisation to the Federation Starfleet. The ISM was formed in early 2385 due to the new Borg offensive. This group was based on the marines of naval vessels of old.
