The Armadillo is by far the most succesful infantry fighting vehicle in the UEF arsenal. It combines great mobility, all around protection, modest firepower and it is easy to repair and manufacture. The features which led to the Armadillo becoming the support vehicle of choice boil down to the protection its passengers enjoy, especially from IEDs (Improvised Explosive Devices) which have been the prime cause of casaulties in peace missions.
Ever since its introduction in 2039 the Armadillo has seen many modifications and upgrades allowing it to keep its technological edge. For all its virtues, an incident with a poor radiation shielding on one of the Armadillo variants armed with an experimental Plasma Destroyer caused quite bit of notoriety among mechanised infantry regiments. Needless to say the variant was immediately retired and has never been re introduced ever since.
In the game
The Armadillo IFV is currently the most heavily armoured unit in the game with an impressive armour value of 7. Coupled with the significant firepower the 40mm Autocannon brings, the Armadillo is an entity on the battlefield that cannot be ignored. It enjoys many synergies with nearby friendly infantry, including the ability to activate alongside a friendly infantry unit.
The Armadillo is especially good against the Homo Inhumanum as if things turn south it can carry friendly troops away in safety.
