Virgo Prohibition

The Virgo Prohibition is a Vex programming collective situated on Mars. Prohibition units can be identified by their dark, metallic-blue frames.

Vex-Cabal War
These guys are the main force that fought the Cabal in the Vex-Cabal War. They were constantly assaulting the Exclusion Zone but made little progress and neither did the Cabal. However, they didn't care. Every day they would throw themselves at the Cabal and even though they would suffer heavy losses and got stuck in a stalemate, it seemed as if they had infinite amount of Vex units. Eventually, the stalemate did end and the Cabal managed to push a little bit into their territory and grab a few new beachheads, and even took some Vex structures. It's theorized that their tactics started out as being efficient but like any war, it takes resources. They lost resources and over time their strategy became "throw as many units as you can at the enemy and hope they break."

Red War
During the Red War, the Vex would inform Ghost that the Virgo Prohibition were, in fact, incorrectly programmed for their task on Mars - indicating that the Prohibition has not been losing against the Cabal as part of a deeper strategic play. During the Red War, they were almost annihilated by the Red Legion who landed on the planet and swept through Meridian Bay, destroying most of the units and the gate to the Black Garden. They could've kept going but after The Red Legions defeat in the Red War, they were halted at Hellas Basin.

Structure
This aggressive and relentless Vex Collective is in constant conflict with the Cabal, repeatedly testing the Cabal's Exclusion Zone without regard to their own losses. In spite of the Vex onslaught, the Cabal have managed to expand their Exclusion Zone and control several Vex structures. The Virgo Prohibition's tactics seem to be failing in the short run but due to the nature of the Vex, it is possible that the Virgo Prohibition is simply drawing out the Cabal's strength (as evidenced at Bastion ) and that their losses could be a distraction from a deeper strategic ploy, as it seems unlikely that such an intellect as the Vex could be dragged into a losing war of attrition. Recent events have borne this out as the Prohibition began appearing in greater number in Meridian Bay to protect the Black Garden.

The ultimate goals of this programming remain a mystery but Ikora Rey proposes Vex units can best be described as algorithms, and that the Virgo Prohibition may be the wrong algorithm for the environment, leading to the idea that continued losses will drive the greater Vex network to adapt and improve.

Trivia

 * Praetorians are a part of this Collective, which is unusual because Praetorians are encountered exclusively on Venus and defending the Vault of Glass. It could be because of the timeless nature of both the Vault and the Black Garden that is the result of this.
