Introduction
Successful target engagement with 40mm LV
tube-launched grenades using leaf sight is not easy to achieve, even for
an experienced operator:
- The operator using leaf sights can only estimate the distance up to the target
- Leaf sights have a very short line of sight (distance between front and back sights). This magnifies any aiming error.
- Leaf sights have range setting every 25 or 50m, which does not make an accurate launch possible.
The solution is to replace leaf sights with a Fire Control Unit in order to maximize first-round hit probability.
FN Solution
FN Herstal has designed and developed a Fire
Control Unit, the design of which fully answers the five critical
questions for a successful launch of 40mm grenades, hence eliminating
all factors likely to affect accuracy.
- What is the precise range between the operator and the target?
The FN Fire Control Unit features a laser range finder which estimates precisely the range. - What is the elevation/depression angle between the operator and the target? The FN Fire Control Unit features a clinometer which measures the firing angle.
- Which ballistic trajectory does the 40mm grenade follow during flight.
The FN Fire Control Unit features a ballistic computer which calculates the angle of launch. - What is the correct aiming point?
The FN Fire Control Unit features a moving red reticle sight which gives the correct aiming point.
Operation
- Press the + button to activate the FCU
- Push on the remote LRF trigger
- Aim at the target with the moving red recticle or with the rifle sight
- The range is shown on the display screen when the remote trigger is released
- The moving red reticle appears in the sight with the correct firing angle
- Align the red reticle on the target
- Fire
