The
FMU will provide organic fire support to the Swedish Army's
six mechanised manoeuvre battalions and it is expected
that each battalion will have a platoon-sized unit as
its main indirect fire support weapon with a total requirement
for up to 24 systems.
The 120 mm
FMU will replace the dismounted, conventional towed mortar
m/41F systems that are currently deployed and will use
120 mm high-explosive ammunition with maximum ranges of
6,000 m (58C/58Z) and 8,200 m (86Z). It is not required
to fire the Strix top attack 120 mm projectile, which
will have passed its shelf life by the time the new system
is introduced. Requirements include the capability to
fire illumination and smoke rounds and, in the future,
precision-guided versions and bombs fitted with a course-correcting
fuze for increased accuracy.
