Actually the Mechanised Igla do not operate alone but as a batt
perhaps 4~6 with a mixed of IFU (Intergated Fire Unit) and
WFU(Weapons Fire Unit) and not neccesary together but spread out to
cover the AO.
Weapon Fire Unit (WFU ) has the 4 Igla lanuchers, IRST optronics
for targeting ,and network computer....
Next we have the Intergrated Fire Unit (IFU), it's not only have
what the WFU have as montioned above but extra thing like the
surveillance/search & tracking radar( the dustbin like
radardome), IFF and battle management system ( a wireless network
computer).
So for example now say a battery of 6, and say 2 IFU and 4 WFUs in
that battery and they are operating together with CAD giving air
defence cover for the CAD in that airspace sector.
So it represent a great improvement over the RBS-70 on V200 with
Giraffe radar.
And the system itself does not mean that it could only operate
Igla, if it is neccessary , it could be upgraded with other better
VSHORAD missile in the future while retaining the all the other
major system like radar, BMS, IRST optronics etc.
In fact , it is quite similar to the German Ozelot.
The PK of Igla is abt 60% and 40& with ECM but when 2 missiles
is launched , it will increase by another 50%.
According to what I have heard , Igla was chosen becos it is cheap,
in fact very much cheaper than for example the Mistral, one of the
VSHORADs in our inventory.
So using surplus hull of M113s with the introduction of BX,
Mechanised Igla means great saving for SAF than to buy foreign
system.
