The 360th Marine Strike Group (aka the Spirit Riders) is a detachment of STARFLEET Marines permanently stationed aboard the USS Dauntless.

Beginning in Region 2 The Spirit Riders were the 698th MSG with BGEN Deb Kern as the OIC. As BGEN Deb Kern Dropped out of SFI for a time, COL Jack Kern took over the MSG. It was under COL Jack Kern's leadership that the MSG moved to Region 8. The Spirit Riders then became the 360th MSG.

In June of 2008 Deb Kern rejoined SFI and became the DOIC of the 360th and the 8th Brigade. Upon Deb Kern's death in July of 2008, MCAPT Shawn Van der Berg became the DOIC of the MSG and Brigade.

The Marines are effectively added security for the ship and landing parties.

As of the end of December COL Kern has transfered from the Dauntless to a meeting chapter near where he lives and has stepped down as the Spirit Riders OIC.

MCAPT Paul Nott is the current Spirit Riders OIC.
