Video shows Iranian boats swarm US Navy ships - CNN Video

Looks like it works, properly!

SGT Mary G. - It will Definitely Screw Up Your Day! 1 Round, 2 Rounds at Most sinks everything I've seen the 5 Inch 54 Used on. Now for Fun and to Waste Time and Ammo the Gunners Mate will Light into things with the 50 Cal, 60 Cal and Chain Gun but when that Gets "Old" they Finish the Job with the 5 Inch 54!

SGT Mary G. - One Video that I Suspect will never See the Light of Day! A Fish Factory Ship turned into a Drug Manufacturing Plant, Intercepted by Pig Boat, Mighty Ark while doing LEDO (Law Enforcement Drug Operations) Took a 5 Inch 54 Round and Caught on Fire. Crew Jumped Overboard, Rescued by the Ark. Then Lit Into with Everything the Ark had to Eliminate a "Hazard to Navigation".

SGT Mary G. One of the Fun Parts of My Job, I've Seen Videos that Not Many Other Human Being will Ever See! LOL!
