Question - Fire Control and Range Finders

[Suhiir]

According to Mobhack Help :

Fire Control - This affects accuracy, especially against moving targets. Values over 99 are fire control radars, with 101 being better than 100. Field changes colour if AAA radar is issued. AAA radar is only worthwhile for AA units, obviously - SP SAM, AA guns, SP AA guns. SEAD aircraft seek out units with active AAA radar - there is no EMCON in SP. Anti-radar missiles may destroy the radar, if not the firer. (As a reference point, 5 was used as a maximum in WW2 data - e.g. king Tiger )

Fire Control of 100+ is radar
Note that FC101 is FC 1 with Radar, but can track planes through smoke and darkness.
Only AA systems with radar get targeted by anti-radiation missiles, and they seek these out automatically . There is
no need to point an ARM equipped plane at anything specific on the map.
Radar equipped AA weapons WITHOUT Thermal Imaging sights should NOT see ground targets through smoke,
only helos and other planes.

Range Finder - This makes hitting targets easier, especially for firers who did not move. 20 is the level for laser range finders, use 6 for the ranging coaxial rifle calibre MG as used in UK tanks, or 8 for a ranging .50 MG as used in Chieftains. Use around 6 to 10 for optical range finders as in the M48/M60/Leo 1. values under 5 tend to be used for WW2 type tank sights. For reference - 4 was generally the max value in SP 1 (e.g. panthers) barring some specials (e.g. 8 for the Nashorn, which used a stereo optical range finder of artillery observer type).

**********

Looking at various OOB we see Fire Control-Range Finder values of :

0-0 Infantry units
0-0 Pedestal / pintle mounted weapons on vehicles
1-1 Tripod mounted infantry weapons with a T&E (i.e. machineguns)
2-2 The M40 106mm Recoiless Rifle with it ranging .50cal
3-3 For "foxhole" type fortifications
5-5 For "bunker" type fortifications
10-10 Snipers (as opposed to just "mere marksmen")
15-16 Chieftain Mk 2
20-16 Chieftain Mk 3

OK, we have the above listed information and "standards" for SPMBT.
I assume the reason for giving vehicle pedestal / pintle mounted weapons values of 0-0 is that while they're effectively mounted on tripods they lack a T&E (Transversing and Elevating mechanism).
I assume the values of 3-3 or 5-5 given to fortifications represent the range cards, cleared fields of fire, etc. common to fortified positions.

What I'm not about is the value of 2-2 given to the M40 106mm RR (and for that matter the SMAW with it ranging 9mm). Mobhack Help seems to indicate they should have a Range Finder value of 6 to 8.

Also, should wire guided ATGM's perhaps have a Range Finder value?

Thoughts?
