I noticed that in many tanks the gunner's sight is larger than commander sight. What capability difference would that cause? Also, by attaching sight to RWS do you mean like what the Russians do with T-90M commander sight? I think they did it the other way round tho.I really feel like they missed a trick here with the RWS design.
They could easily have included a modular add-on commander sight to the RWS, such that if you opt to have the RWS installed, it will effectively become the commander’s sight. You can easily add the full multi-sensor commander’s sight as a fixed unit in front of the actuator box, and you pan the whole RWS. You can retain the basic model commander sight in its normal place as a back-up unit.
Doing so would have the benefits of:
- elevating their commander sight to give him better field of view
- remove the blind spot to the rear that the RWS creates with the current commander’s sight set up.
- ensures that the RWS can engage targets immediately upon target detection
The only downsides I can think of would be cost, and potential issues with LOS due to the different in height between the commander sight and gunner sights. But both those issues could be easily resolved.
If cost is a major issue, they could do away with the back-up commander sight at the normal location altogether. This will actually yield a net saving as you do away with the separate sight system for the RWS.
As for potential LOS differences, well if they retained the back-up commander sight in its normal position, that could be slaved to the RSW, and the two images combined via software to add a virtual horizon to the RSW sight picture showing the LOS of the commander sight and thus giving a good indication of the gunner’s LOS limits.
Luckily this is an easy thing to fix with retrofits.
