Yeah that's going to work! Modern AT weapons have 2 stage warheads to defeat reactive armour where stage 1 fires on nearing the vehicle followed by stage 2 on impact. Against a shipping container I'd imagine stage 1 will punch a hole and stage 2 will impact the armour. It's not going to be possible to deploy reactive / active defense systems armour as well as a shipping container I would have thought as there's no way of detecting the incoming round with the container in the way for active defence nor deploying the projectile plus you risk damaging the tank with the reactive armour explosion as it's enclosed. So I can't see these containers doing jack against a modern 2 stage round.

The Russians made great play of the Challenger they destroyed a couple of years ago but the simple fact is, non of these tanks were ever designed to be protected from drone warfare and thus all have vulnerabilites - in the Challengers case it was the engine bay from a direct behind strike - something that will kill any tank although they claimed the Challenger was weak and overhyped. I imagine going forward the next generation of tanks will have active kill systems capable of detecting and destroying drones and offering 360 degree protection. Unil then, all tanks will be vulnerable.
