District 9 Wiki

The Multi-National United Security Force is the main source of security in District 9.


The MNU operates its own private military, (albeit euphemistically monikered as "private security"), the strength of which appears to rival the might of the armed forces of the most developed nations of the world. The security forces are split into two groups: the primary body, which shares the same name as its parent organization, MNU Security Force, and the elite subgroup, The First Reaction Battalion.

Types of soldiers[]

Primary soldiers[]

The main body of MNU's security forces consist of the primary soldiers of the MNU Security Forces. These personnel are security guards who are armed with Vektor CR-21 bullpup rifles. They man checkpoints and are the primary source of security in District 9 and the MNU Headquarters Building. Little is known about the primary soldiers, other than the fact that they escorted MNU Agents during the District 9 eviction and relocation process. Thomas is one of them.

First Reaction Battallion

The more elite First Reaction Battalion members are armed with state of the art weapons like the FN SCAR and Scorpion class body armor with biowarfare protection, while their ground vehicles appear to be mostly belong to MRAP projects. These units work in groups and are meant to deal with the aliens through lethal force. They are mostly seen deployed in teams of two from small and quick helicopters, that drop them into hot spots where they subdue the hostile aliens they come across.


The security force uses numerous vehicles to transport both themselves into the field, and to move the aliens under MNU's "care" to different locations. This is also the case when deploying armed, lethal, force against the nonhumans. (Which, given the callous brutality of contractors, meted out with callous indifference to alien wellbeing, is more often than the official statements of the spokespeople of Multi-National United allege.) Ground vehicles consist of various Toyota Hilux pickup trucks, Reumech OMC Casspir transport trucks, Mechem Tapir, and a few others. The security force also use helicopters for air transport, especially when inspecting the giant alien ship. Helicopters consist of the Eurocopter EC130 and the Aerospatiale SA 330 Puma.


  • According to Neil Blomkamp in his commentary on the DVD of the movie, the First Reaction Battallion was inspired by Executive Outcomes, a defunct South African private military company that was very active in the African continent during the 1990's. Many of its former members (including its founder Eeben Barlow) formed the new PMC STTEP .
    • In the year 2020, Executive Outcomes was resurrected by Eeben Barlow after twenty-two years of defunction.
