The 81mm Mortar is on issue to all infantry battalions, with each battalion
having a mortar platoon with three or four sections; and each section deploying
two mortars.
These mortars are the battalion's organic Manoeuvre Support Firepower
and can be used to put a heavy weight of fire down on an objective in an
extremely short period.
Mortar fire is particularly lethal to infantry in the
open and in addition is very useful for neutralising dug-in strong points or
forcing armour to close down.
The fire of each mortar section is controlled by the MFC (Mortar Fire
Controller) who is usually an NCO and generally positioned well forward with the
troops being supported. Most MFCs will find themselves either very close to or
co-located with a Task Group Commander. The MFC informs the base plate (mortar
position) by radio of the location of the target and then corrects the fall of
the bombs, directing them onto the target.
Mortar fire can be used to suppress enemy positions until assaulting troops
arrive within 200-300 m of the position. The mortar fire then lifts onto enemy
counter attack and supporting positions while the assault goes in. The 81mm Mortar can also assist with smoke and illuminating rounds.
The mortar is carried in an AFV432 or a Truck Utility Light or Medium and if
necessary can be carried in two, man-portable loads of 11.35 kg and one 12.28 kg
respectively. In the past, infantry companies working in close country have
carried one 81mm round per man when operating in areas such as Borneo where
wheeled or tracked transport was not available.
For Air Mobile and Air Assault
operations mortar rounds are issued in twin packs of two rounds per man on
initial deployment. These are used as initial ammunition resources until
palleted ammunition loads can be flown in.
The L16A2 81 mm Mortar
has undergone a mid life upgrade (MLU) to embrace recent technological
developments. The inclusion of the new SPGR (Specialised Personal GPS Receiver)
and the LH40C (Laser) combine to make the new TLE (Target Locating Equipment).
This generates a significant enhancement in first round accuracy and the ease,
and speed with which accurate fire missions can be executed. Additionally, the
equipment reduces the number of adjustment rounds which will be used and lead to
greater dispersal of mortar barrels, thus increasing protection for the mortar
crew soldiers.
Plans continue to develop further synergies with The Royal Artillery to improve
the existing levels of co-ordination between Artillery and Mortars in fighting
the indirect fire battle.
Improved performance ammunition with greater lethality against buildings, armour
and equipment is expected to be in service within the next two years.
