The Raid on Solcrum was an attack by the squad of the SSV Normandy on a geth heretic base located on the moon Solcrum that occurred during the Armstrong cluster campaign. Due to the growing threat of Saren's Alliance, and the ever increasing incursion of geth heretic forces present in the Armstrong cluster which was likely a precursor to invasion, the Raid on Solcrum was the fifth of five engagements to expel Saren's troops from the cluster. The fifth of these engagements and the final ground engagement, Marcus Shepard and his men managed to neutralize the geth on Solcrum and destroyed their base of operations, ending the threat they posed.
