Operation Revival[edit]

Wave Five[edit]

The Steel Vipers won the right to re-take Twycross during the Fifth Wave of Operation Revival.[1]

The actual attack was undertaken by the 423rd Assault, 428th Assault and Ninety-Fourth Battle Clusters. Landing under the cover of the Diabolis sandstorms, the 423rd and 428th defeated the Tenth Lyran Guards RCT by using the Viper's Maw tactic, while the Ninety-fourth engaged the Ninth Federated Commonwealth RCT and forced them back to the spaceport.[2][1]

The battle was over in a matter of hours.


The 428th was almost wiped out on Tukayyid.[2]

Post Invasion[edit]


Ejection from the Inner Sphere[edit]



As of 3061 the Commanding Officer was Star Colonel Timothy Gerard, who had been in command since at least 3058.[2]


The cluster is experienced in the use of the Viper's Maw tactic and can fight also in conjunction with the other cluster of the galaxy effectively.[2]
