The unified military and naval forces of the Bacrana system were known as the Bacrana System Defense Force. Centered on the planet of Bacrana, the BSDF initially demonstrated allegiance to the Galactic Empire. However, this loyalty dissolved when Imperial authorities within the system began mistreating the local population. Following a protest of several thousand in the capital city of Amma, the BSDF declined to disband the demonstrators. Moff Lesan Ramier then had to assemble his own troops to deal with the defiant crowd. Consequently, the Moff commanded the BSDF to halt all operations. Trep Reskan, the leader of the BSDF, rejected this directive and relocated almost the entire Defense Force to the Tel system. From this new base, the Defense Force initiated a guerrilla war against Moff Ramier. Their actions proved so effective that the Alliance to Restore the Republic reached out to Reskan, inviting his group to join their ranks. The Defense Force accepted the Alliance's offer, thus becoming allies of the larger organization.
