AMOS or Advanced Mortar System is a 120 mm automatic twin barrelled, breech loaded mortar turret. AMOS has been fitted to a wide range of armoured vehicles such as the SISU XA, AMV 8x8, Combat Vehicle 90 or Combat Boat 90. AMOS can fire 26 rounds in one minute and the first 14 rounds can be set to impact on the target at the same time. This happens by adjusting the angle and power of the shots and carefully calculating the time between the shots. The first rounds are shot with higher angles and loads of propellant so that the rounds fly a high arc. The next rounds are shot a couple of seconds afterwards with a slightly smaller angle and with less gunpowder so that they fly a lower arc but fly as far as the first rounds. This can be done seven times in a row, always adjusting the angle and power, so that the result is that all the 14 rounds hit the target simultaneously. The adjustment between the shots is done by a computer. The strike of one AMOS unit roughly equals one strike of an artillery battery.
An AMOS turret has a full 360-degree field of fire at elevations between -3 to +85 degrees. AMOS is capable of both conventional indirect fire and direct fire for self-protection.
AMOS is manufactured and marketed by Finnish/Swedish Patria Hägglunds, a joint venture between Finnish Patria and Swedish BAE Systems Hägglunds.
Ammunition for AMOS includes the Strix guided round.
There is also a lightweight version called NEMO (NEw MOrtar).
