|Unit Profile (as of 3061)|
|Nickname||The Deadly Venom|
|Parent Formation||Alpha Galaxy|
Initially performing admirably but unremarkably during the fighting on Arcadia as part of Klondike, the Fourth Steel Viper Binary took serious losses from a counter-attack by forces of the Republic of Rand at the end of the conflict. These losses would ensure that the Fourth was the last of the four Clusters to recover and expand to full strength, instilling in the Guards a strong desire to prove itself in comparison to other more storied units.
During the Trials preceding Operation Revival, the Fourth represented the Steel Vipers. They defeated Clan Burrock, Clan Diamond Shark and Clan Coyote, but lost to Clan Jade Falcon in the placement trials. They lost their battle with Clan Ghost Bear in the corridor trials, but their performance was good enough to earn them a place as the reserve Clan.
Despite the Fourth's elite reputation, the unit's only involvement during Operation Revival was a series of rear-guard actions on Jabuka in December 3051, the apparent snub by pro-Warden Khan Natalie Breen and Alpha Galaxy Commander Christopher Ahmed due to its brash and pro-Crusader commander Brett Andrews.
Though damaged in the Battle of Tukayyid the Fourth Guards were quickly brought back up to full strength. The Fourth Guards staged a Trial of Possession for Blackjack in June 3052 in conjunction with the Alpha Newt and Alpha Solahma Clusters.
In November 3052, the Fourth Guards participated in another attack on the Jade Falcon Occupation Zone, this time invading Blair Atholl together with the 400th Assault Cluster. The two Clusters destroyed the Jade Falcons' Eighty-Ninth Striker Cluster and forced the remnants of the Ninety-fourth Striker to retreat off world.
Between 3053 and 3061 their homeworld was Blair Atholl, from which they struck at many Lyran Commonwealth worlds. As they became familiar with the Inner Sphere tactics, the Fourth developed their reputation as Alpha Galaxy's rapid reaction force.
Ejection from the Inner Sphere
The Fourth Guards saw their commander, Star Colonel Brett Andrews, promoted to saKhan in 3058. Star Colonel Angela Masters took command just before the Vipers began their assault on Jade Falcon worlds. The Fourth performed well during the initial and second waves, but the Falcons quickly responded. The Falcon's Delta Galaxy pursued the Fourth Viper Guards all the way to Waldorff, where the Vipers were destroyed fighting alongside the Triasch Keshik. No effort was made to rebuild the unit as the Vipers returned to the Clan Homeworlds.
Between 3051 and 3058, the Fourth was commanded by Star Colonel Brett Andrews. Andrews would subsequently rise to the position of Khan and eventually ilKhan. In 3061 the commanding officer was Star Colonel Angela Masters.

- 5 Trinaries
During their time in the Occupation Zone, the Fourth Viper Guards loathed Inner Sphere soldiers, and reduced their short range to-hit numbers by 1. Their disgust and fury when fighting Inner Sphere troops results in a 1 point penalty to Initiative. Regardless of opponent, when randomly selecting units each Trinary of the Fourth Viper Guards must contain at least one Star of Elementals.
