The biggest lesson for any military due to this Azer-Armenian war is that if the Drones are used correctly, the Tanks are a sitting duck in front of drones. Pakistan Military needs to learn valuable lessons from this.
One option is add a laser warning reciever + smoke generator-cannister dispenser to tanks as a passive defence. It wont work on only optical targeting without laser targeting though which only multiband radio jamming can work up to a degree.
Also laser warning reciever wont work if the pointer is targeted to ground and at the last second to the tank as a tactic. So laser warning reciever should be added to front back and side parts of the tank checking the ground as well
Smoke ofcourse wont work if it is only optical band. It should cover IR band like for example white phosphorus smoke screen or some other hot gas. Nearby infantry has no option to run away after laser detector activates.
Better attach a small balloon+laserwarningreciever by wire to one of the vehicles . It will continiously detect a larger area for laser pointers with no fuel need
Another update: fire and forget missiles like hellfire mmwave radar seeker would be a problem. In that case radar warning reciever as in planes is also necessary. Chaff would also work to a degree if it suspends in air and moves slowly the target on the hellfire agm would appear larger and more difficult to hit. Usual jamming tactics like towed emitters would work to a degree as in aircraft countermeasures.
Also IIR guided air to ground bombs-missiles would be an issue. For example israeli opher iir guided bomb or missiles connected to this approach. These bombs are fire and forget as they are released over the course of the target by aircraft and missile is locked onto target ir signature after launch. In that case it can lock onto anything nearby the tank as well like for example an infrared decoy emitter nearby.
One option left for the aircraft is to radio guide the missile very close to target until the missile seeker locks on to the original intended target with its passive IIR/optical seeker. That would be the most difficult to detect by the target as there is no active emitter like laser or radar to paint the target. In that case somehow tank needs to detect the incoming missile(by itself or informed by a seperate radar/IIR carrying specialized vehicle scanning around) and immediately employ hot smoke + chaff + move around to block the IR/optical/radar vision of the uav as well as the missile itself. There is no effective measure against Gps, inertial navigation system for static targets but to move somewhere else immediately after detecting something is coming.
Last edit to sum up:
tanks can employ hot smoke (white phosphorus) to block IR and optical sight. Also they can deploy chaff continiously to
break radar lock. The earlier the measure is triggered the better chance of survival.
laser guided missiles : Laser warning reciever would alert the tank to deploy measures.
radar guided missiles: Radar warninig reciever would alert the tank for measures.
optical-radio guidance in midcourse or full radio guidance: Radio signal locator/detector seperate vehicle(a very cheap version of kulchuga-vera to detect something above nearby sends radio signals which is not own airforce to trigger nearby tanks defensive measures.
Full infrared guidance without radio signals: infrared decoys near tanks. Missile needs a large iir sensor to distinguish
the real target from decoy from 7km altitude making it expensive and large that can be detected after launch by ground radars on tank defense radars-vehicles
