Most of the Soviet/Russian tanks use quite complex FCS with long, boring names, but in Arma 3 we have basically 8 main scopes, sometimes combined in some tanks (like T-90A 06’ has both 1G46 and Sosna-U scopes).
So here is the list of thing we want to touch in this guide:
Scopes:
- TSh2B-32P (T-55A)
- TDP-K1 (T-72B 84’/85’/89’, T-80)
- 1G46 (T-80A, T-80U/U(45M)/UE-1/UK/UM, T-90 92’)
- 1G42 (T-80B/BK, T-80BV/BVK)
- 1A40-1M (2S25)
- Agava-2 (T-80UK/UM)
- Sosna-U (T-72B3, T-80UE-1, T-90A 06’)
- OPFOR Vanilla FCS (T-100 Black Eagle)
Firing systems:
- Manual FCS adjusting
- Autoloader and Semi-Autoloader
- Target Tracking System (Sosna-U)
1. TSh2B-32P (T-55A)
You can see “mechanical” indicators of each type of ammunition under a fixed aiming line, aiming chevron and physical rangefinder, which is completely useless since it is marked starting from 1200m.
The tank has the only mechanical scope and no fancy laser stuff, so it is always good to have someone calling you ranges outside of the tank.
So to fire properly gunner should:
1) Load a shell
2) Aquire range
3) Manually adjust range by pressing Ctrl+PgUp, Ctrl+PgDn (by default) according to the chosen type of ammo.
4) Point ^ thingy on target
5) Shoot
Re-adjust scope every time you switch ammo type. Each shell has its own ballistics.
2. TDP-K1 (T-72B 84’/85’/89’, T-80)
You can see “mechanical” indicator of distance and shell load indicator on top.
The red circle in the middle is a Rangefinder and it’s aligned with the axis of the cannon.
So to fire properly gunner should:
1) Load a shell
2) Point red circle on target
3) Press “T” (or any button bound on “Lase target” action) to find range to target
4) Wait for FCS to calculate corrections and adjust scope
5) Point ^ thingy on target
6) Shoot
Re-adjust scope every time you switch ammo type. Each shell has its own ballistics.
ATGMs will follow the red circle, so you don’t need to adjust scope if you shooting ATGMs.
The rangefinder will not adjust range for coax but scope itself has reticles to make your life slightly easier.
3. 1G46 (T-80A, T-80U/U(45M)/UE-1/UK/UM, T-90 92’)
You can see the digital indicator of distance and shell load indicator on the bottom.
^ thingy is aim point and a Rangefinder.
So to fire properly gunner should:
1) Load a shell
2) Point ^ thingy on target
3) Press “T” (or any button bound on “Lase target” action) to find range to target
4) Wait for FCS to calculate corrections and adjust scope
5) Shoot
Re-adjust scope every time you switch ammo type. Each shell has its own ballistics.
Unlike FCS of T-72 on this one, you have to re-adjust scope even for ATGMs.
The rangefinder will not adjust range for coax but scope itself has reticles to make your life slightly easier.
4. 1G42 (T-80B/BK, T-80BV/BVK)
You can see the digital indicator of distance and shell load indicator on the bottom.
^ thingy is aim point and a Rangefinder.
So to fire properly gunner should:
1) Load a shell
2) Point ^ thingy on target
3) Press “T” (or any button bound on “Lase target” action) to find range to target
4) Wait for FCS to calculate corrections and adjust scope
5) Shoot
Re-adjust scope every time you switch ammo type. Each shell has its own ballistics.
Unlike FCS of T-72 on this one, you have to re-adjust scope even for ATGMs.
5. 1A40-1M (2S25)
You can see the digital indicator of distance and shell load indicator on the top.
Cross on the reticle is aim point and a Rangefinder.
So to fire properly gunner should:
1) Load a shell
2) Point cross thingy on target
3) Press “T” (or any button bound on “Lase target” action) to find range to target
4) Wait for FCS to calculate corrections and adjust scope
5) Shoot
Re-adjust scope every time you switch ammo type. Each shell has its own ballistics.
You don’t have to re-adjust scope for ATGMs. ATMG will follow cross marker.
6. Agava-2 (T-80UK/UM)
You can see the digital indicator of distance and shell load indicator on the top left corner.
Cross on the reticle is aim point and a Rangefinder.
So to fire properly gunner should:
1) Load a shell
2) Point cross thingy on target
3) Press “T” (or any button bound on “Lase target” action) to find range to target
4) Wait for FCS to calculate corrections and adjust scope
5) Shoot
Re-adjust scope every time you switch ammo type. Each shell has its own ballistics.
You don’t have to re-adjust scope for ATGMs. ATMG will follow cross marker.
7. Sosna-U (T-72B3, T-80UE-1, T-90A 06’)
The aiming reticle has two stages. If it looks like “+” or “cross” – chamber is empty or loading. If it looks like “[⊥]” – chamber is closed and you are ready.
So to fire properly gunner should:
1) Load a shell
2) Point “⊥” thingy on target
3) Press “T” (or any button bound on “Lase target” action) to find range to target
4) Wait for FCS to calculate corrections and adjust scope
5) Shoot
Re-adjust scope every time you switch ammo type. Each shell has its own ballistics.
ATGMs will fly at the tip of the “⊥” of “[⊥]” scope or in the middle of “+”.
8. OPFOR Vanilla FCS (T-100 Black Eagle)
This vanilla stuff is pretty much self-explanatory. You have Aiming/Lasing point, the icon with your gun position relative to the hull and commander camera. Also you will have a target speed if you are targeting a moving target.
Cross on the reticle is aim point and a Rangefinder.
So to fire properly gunner should:
1) Load a shell
2) Point cross thingy on target
3) Press “T” (or any button bound on “Lase target” action) to find range to target
4) Wait for FCS to calculate corrections and adjust scope - little box (Ready to Fire box) on the top left of the range digits will appear.
5) Shoot
Re-adjust scope every time you switch ammo type. Each shell has its own ballistics.
Manual FCS adjusting
ALL of this FCS can be adjusted manually. You know, for long-range indirect fire, for example.
To do it gunner should press “B” and he’ll see this:
As you can see there is not much going on.
Switch at the bottom is angle sensor. Keep it on and everything will be okay.
Two dials on top for adjusting range in 100m and 1000m respectively.
Do not forget to return every dial in lowest position after you ended playing with it, otherwise, it will fuck up your aim.
Autoloader and Semi-Autoloader
It’s system that loads tank shells in the gun. Automatically. Whoa, technology!
All Russian tanks with autoloaders have this “dial” on gunner’s screen. You can switch between round types via scroll wheel OR by pressing “X”. Pressing “X” will cause dial to turn and, well, it chooses the type of shell you want:
«О» - HE-FRAG
«Б» - APFSDS
«К» or «H» - HEAT
«У» - ATGM
All FCS’s have shell load indicator. Т-72’s – big red thing on top, others – small LED to the bottom.
If it’s lit – chamber is closed and you are free to fire. If it’s dark – it’s either still loading or chamber is empty and you can switch shell type.
But be aware ONCE SHELL IS LOADED YOU CAN NOT SWITCH TO ANOTHER TYPE OF SHELL.
You can still turn “dial”, though. But shell type switches only after your shot.
For the initial load, you have to select the type of the shell via scroll wheel, because default all Russian tanks initially have no shells in the closed chamber.
Semi-Autoloader
Waits for gunner’s command to load a round in the chamber.
Gunner has to press “R” to load selected type of the shell after every shot.
Full Autoloader
Autoloader has the switch for modes. You can switch between modes by pressing “Z”.
If the switch is UP (“ВКЛ” position) autoloader will automatically load a shell into the chamber without you pressing buttons and will continue load this type of shell until it runs out of shells of this type. But it won’t stop – it’ll just load shell of next type in the list.
If the switch is DOWN (“СЕРИЯ” position) autoloader will work in semi-automatic mode and would be waiting for a gunner to press “R”.
Target Tracking System (Sosna-U FCS)
TTS is a special part of Sosna-U FCS. Has two abilities: stabilize gun on one point on the ground (like on helicopters) and lock-on target mode. Lock-on mode works only in thermal mode.
To enable lock-on target, the gunner has to:
1) Zoom to the end for «АСЦ» until TTS state turns into «ГОТ»
2) Aim at the target
3) Hold “T” for a second until «ГОТ» turns into «ВКЛ» and scope locks on the target
4) Shoot
Since it’s locked you can move aim point for specific point on the target.
Especially effective on medium-long distances against moving targets like tanks or helicopters.
Works with any type of ammo, even with ATGMs. But keep in mind – since it is a laser-based system it could be obstructed by foliage or buildings.
