The first hit was definitely a rocket which would have a relatively small warhead with a directed charge designed to transfer as much energy as possible into penetrating the armor.
I guess the shawaz is also a directed charge of some sort but he definitely tossed it up like it was just a big bag of boom.
That thing blew the fuck up. The shockwave looked like a 155mm artillery round going off. The distance you want to be from 155mm artillery for your health is as far away as possible. If the first Merkava popped a hatch to engage the attackers, that explosion on the second tank could very well have killed surviving crew in the first.
I hope the guy made it out uninjured and that his hearing comes back soon.
It's off the grid
