Mobile Infantry (MI) is a fictional military force in Robert A. Heinlein's novel . The MI appear in the movies Starship Troopers , released in 1997, the 2004 sequel, Starship Troopers , the 2008 film Starship Troopers 2: Hero of the Federation and the TV series Starship Troopers 3: Marauder . The MI is portrayed differently in each version, a constant element is their depiction as Roughnecks: Starship Troopers Chronicles space marines, soldiers who undertake infantry operations after insertion onto a planet from space. The MI trademark powered armor of the novel appears only in the last films as rough prototypes.
The Mobile Infantry is part of the
Terran Federation military. In the original source novel Heinlein uses it to compare and explore the differences between two races, one of free individuals (humankind) vs. a collective race (bugs). Heinlein's MI is a volunteer force that resembled the Roman Legions, or modern day US Marines.
Role playing game [ edit ]
Starship Troopers role-playing game (RPG) developed by Mongoose Publishing and the Starship Troopers first-person shooter (FPS) make an amalgamation of the Mobile Infantry of the movie and the Roughneck Chronicles series with light infantry from the movie being supported by elite power suit equipped warriors for elite operations. The "light troopers" were envisioned as cheaper alternatives to the more fully trained, power armored, "true" Mobile Infantry. 
Influence [ edit ]
Heinlein's description of the MI's powered armor, directly and indirectly through his Japanese translator
Tetsu Yano, influenced the depiction of powered armour and mecha in manga and anime, e.g. . Mobile Suit Gundam
The units equipped with very similar powered armor in
John Ringo's Legacy of the Aldenata series are also referred to as Mobile Infantry.
