Consider these options;
1] sabra tank with 105mm main gun and 60mm mortar (7.62mm and 0.50cal HMG included) both has direct and indirect capabilities in one platform. 60mm mortar is located on the left most side of the turret. or loader side. It can hit targets inside trenches, in ditches, in irrigation canal, foxholes or behind building , behind walls and rooftops. It can lay smoke screens for infantry advance . A combination of firepower from 105mm and 60mm mortar plus HMG and GPMG within the direct control and discretion of one tank commander without time delays is a big factor.
it is no longer constrained on using o.50 HMG to hit rooftop targets possiblity of stray 0.50 slugs hitting populated area 1km or 2km behind the target. It can lobbed 60mm mortar on the rooftop. 60mm mortar can add another dimension for tank capabilities.
2] For tank with direct fire only. There will be Delays in fire support.- this is a battlefield reality. Indirect fire support from 81mm/ 120mm mortar and 105mm howitzers needs higher ups approval. Needs to prep the rounds and calculations need double checking ,these preps and checking consumes time. According to tank crews i interviewed, it takes time, 30 minutes or even an hour. Maybe they exaggerate a bit, but delays can kill. Try to observe the procedures followed by artillery team before sending rounds down range and compare the attached video (showing IDF crew firing 60mm mortar). It is faster. Procedures are followed for the safety of the troops down range and assurance those rounds will not cause collateral damage.
Let me qualify, i am not against active protection system, sniper detection system, or bmpt terminator. Im with it.
adding a 60mm mortar in the sabra turret will not cost much(they might even put it as free add-ons). with one small weapon, you add another capability for one tank.
An indirect fire capability for tank is an asset not a burden.
the 81mm/120mm mortar team might appreciate that sabra tank wont call often for fire support bcoz it can handle small anti-tank teams hiding behind walls or ditches . It can handle some small targets . It might bridge some of that capabilities in limited scope.
Let me summarize my points. An added Indirect fire capability for a tank is real asset not a burden. There is always time delay from artillery support (81mm mortar is classified artillery)for it needs BATCOM approval(at the least). Delays can cause lives.
If there an issue on space inside sabra turret, let Elbit confirm it and ask them how they can do about it. If Elbit says no-cannot put for space constrain, then the discussion is closed .But if Elbit says, they can do it, why limit the capability of sabra tank .
And if Elbit ,can offer sniper detection system with minimal cost. Im with it.
Jokingly aside, it Elbit can make sabra swim and fly at the same time, im with it.
