|Nickname||The Silent Strikers|
|Parent Formation||Gamma Galaxy|
In April 3053, the Fifty-first attacked Trell I with the intention of stopping Jade Falcon raids that originated from there. On landing, the Fifty-first found no trace of their opponents, the Eighth PGC, and subsequently walked into an ambush. This triggered a four-day long battle that ended in a Steel Viper victory, but at the cost of serious casualties.
During the withdrawal from the Inner Sphere the Fifty-first took heavy casualties prompting the Khan to disband the unit and transfer the survivors to the Ninety-fourth Battle Cluster. Plans to rebuild the Cluster were drawn up, but by 3067 had still not been implemented.
