As soon as firing begins, you choke on the acid-smoke that burns your eyes, the gunner and loaders and fire controller all shouting at each other. Trying to wipe away the flood of tears to see the target.
The muzzle blasts, 3 a second, were so strong, my contacts shook off-center when my eyes were open and my nose started bleeding.
The spent casings are red hot, piling all around and burning our feet and ankles. The concussion from the muzzle blasts leaves you numb and I have a permanent ringing in my ears.
All of that in only about 90 seconds of live fire. And, the enemy was only a 25 foot long, unarmed steel shipping container. 
I can only imagine the pounding sailors would take firing on waves of small boats that were firing rockets and small arms back. God bless 'em if they get in that fight, they're better men than me. It's easy to call 'em from the bench, war with the Iranians will be to the death.
