The MBT-90 is a main battle tank developed by AE-Military Vehicle Division in the 2080s for the Berusian Army. The tank first entered service in 2087 and succeeded the earlier MBT-80R as the main battle tank of the Berusian Army. Various versions have served in the armed forces of Berusian and other countries. The MBT-90 was used in the Berusian Civil War by the Loyalist Berusian Army.

A lone loyalist MBT-90 named "Guardian Echo" held back 30 coup'd'etat forces camouflaged MBT-80R's and 2 AH-2 LSH for 2 days until reinforcement AH-35 Hornets and MBT-90's arrived. The tank destroyed 23 of their tanks and 1 AH-2.
The crew was awarded the highest honors in the Federal Republic of Berus - The Mark of Re'liosa
The vehicle is now in the Alderson Military Museum in Neuell.

All models feature digital fire control systems with laser rangefinders, a fully stabilized main gun and coaxial machine gun, advanced night vision and sighting equipment (first vehicles used a low-light level TV system or LLLTV; thermal imaging was introduced later on) and an Area defense system that can alter the flight path of the ATGM away from the tank and destroy RPG's,grenades and nearby IED's, some Block I models have optical camouflage installed in them. The tank has the ability to engage moving targets while moving over rough terrain.
