Mar Sara Colonial Militia

The Mar Sara Colonial Militia was the "home-grown" self-defense and police force of Mar Sara. It frequently used antiquated equipment. It operated mainly independently from the Confederate military.

It was led by several marshals, such as Jim Raynor, and answered to the Colonial Magistrate of Mar Sara.

A branch of the force, led by Marshal Raynor, was assigned to the Wasteland where it protected the colonists who were dispersed there under Confederate orders.

Shortly afterwards, soldiers at Backwater Station came under attack by the Zerg. Alpha Squadron commander Edmund Duke knew of their predicament but made little to no effort to rescue them. Raynor headed out by himself with the Magistrate sending in a militia force, the former personally leading his troops to the Station, rescuing the soldiers and destroying a nearby Infested Command Center.

An angry Duke arrested Raynor and many standing militias. The Confederates refused to engage the Zerg and further hindered the militia's ability to defend the planet by 'liberating' their hardware. The only source of military relief was the Sons of Korhal.

Mar Sara City came under attack by the Zerg. Arcturus Mengsk, leader of the Sons of Korhal, made a deal with the Colonial Magistrate; he would provide transport craft to evacuate the colonists, provided that the militia could hold out that long. Meanwhile the Sons of Korhal rescued Raynor and his men from a Confederate prison ship.

The Magistrate, Raynor and other militia members joined with the Sons of Korhal, which evacuated the planet. The organization ceased to exist due to its fusion with the Sons of Korhal, as well as the destruction of Mar Sara by the Protoss. Later, many of its members joined the breakaway faction of Raynor's Raiders.
