Introduction

The MO-120 is range of towed 120mm smoothbore mortars of French origin. After World War 2 a range of Brandt 120mm smoothbore mortars was developed under the name MO-120. They are known for their high performance and good mobility.

Layout

The MO-120 mortars are conventional muzzle loaded smoothbore mortars. Their design is relatively complex. All MO-120 mortars are based on a triangular baseplate, two leg bipod and a set of two wheels that is either fixed or detachable.

Firepower

The MO-120 mortars can fire a variety of 120mm mortar shells. The performance varies vary per model. The MO-120-60 can be used out to 4.2km with normal shells while the MO-120-LT can fire up to 7 km. The maximum rate of fire is over 12 rounds per minute, although 8 rounds per minute is normal.

Mobility

All MO-120 mortars are based on a two wheel carriage which allows them to be moved in the field by infantry. The lightweight models are especially easy to transport due to their limited weight for a heavy mortar.

Users

The MO-120 mortars have been widely exported all over the world. They remain in use around the world today.

Variants

MO-120-AM-50

The AM-50 is a heavy smoothbore 120mm mortar. It is muzzle loaded and traverse and elevation are adjusted through the bipod. The AM-50 can also be fired from its fixed two wheel carriage when the axles are locked. The AM-50 was replaced by MO-120-LT.

MO-120-60

The MO-120-60 is a lightweight mortar that is based on the AM-50. The base-plate is much smaller and the barrel is lighter.
