AMOS Mortar Description

The AMOS Mortar turret is modular, allowing for integration with most Fighting Vehicles

Due to turret mounting AMOS has a full 360-degree field of fire at elevations between -3 to +85 degrees. Thus, AMOS is capable of both direct fire for selfprotection and conventional indirect fire.

Ammo used in AMOS is conventional smooth bore mortar 120 mm fin-stabilised ammunition with a short stub case added.

AMOS crew normally consists of four men: driver, commander, gunner and loader. Of these, commander and gunner are seated in the turret.

Thanks to its electronic equipment AMOS is capable of fully independent operation, but traditional optomechanical aiming methods are retained as back up

Direct fire capability
Rapid deployment due to instrumentation for vehicle location and attitude; well suited for shoot & scoot tactics
Ballistic protection against infantry weapons and splinters
Muzzle blast and NBC protection Low chassis loads due to recoiling mechanism; suitability for both wheeled and tracked chassis
Suitability for all standard 120 smoothbore mortar ammunition as well as smart guided ammunition
