This. Is. Awesome. Check out 3:35, when they blindly blast away at a stationary ship a few hundred meters away with small rockets.
Or check at 8:12 for the Iranian navy seals, complete with colored snorkeling gear strait from wal-mart.
I could see them using the swarm of small boats in the confined straits, but what gives with the unguided rockets where you have to be a few hundred meters away to hit a stationary target? Swarms of WWII torpedo boats would be much more effective, and they still were not that successful during WWII.
