JDAMs are expensive munitions that require air superiority by the enemy to be used effectively against tanks, also you could counter enemy air to prevent getting hit by JDAMs in the first place. Drones are a lot more prevalent, much cheaper to produce and extremely easy to use that still has the capability to take out MBTs in a single strike. Effective counters against drones could be made a priority IMO.
Firstly, drones are only cheap right now because of open and free trade with China. Not saying it is likely to happen soon, but theoretically China could end the world wide supply of cheap drones and critical drone parts overnight at a stroke with one regulation change.
Countries and militaries need to think really long and hard if they want to make cheap commercial
drones a backbone component of their future war fighting arsenal when they are so ridiculously dependent on China for critical components.
But putting that aside, when you counter enemy manned tac air, do you focus on point defence against incoming munitions or try to hit the enemy launch platform at source before they can spam munitions at you?
The true hard counter to FPVs is not to try to Iron Dome the drones, but to be able to effectively and rapidly go after the pilots as they are both the bottlenecks and Achilles Heel of that entire kill chain. But that’s not a job for tanks, rather new dedicated platforms.
Yes, armoured formations still need to be able to effectively deal with incoming FPVs that slip through or during ambushes, but again, that is down to the formation having dedicated counter drone assets, not for every vehicle in the formation to be able to sole swarms of drones without a scratch.
Countering drones is a desperately urgent requirement for all serious militaries today and in the future. But the correct way to counter drones is with new generation dedicated platforms instead of trying to make every vehicle into real life warhammer superheavies.
