Small arms training?


I recently joined the forum.

I just graduated High School in June. I am seriously considering a mariner career. While researching this I was looking at the unlicensed apprentice program that the SIU offers. It looks good. While browsing through the photo gallery I saw a photo titled Small Arms Training. Is that part of the apprentice program? And why would a non-military mariner need firearms training? I understand that there is a threat from pirates but I had been given the impressions that carrying firearms aboard ship was prohibited.

Any info is appreciated. But, I did not post this to be told “Dont go to sea.” I have seen the cons of this career posted in other threads and have considered them (and am still considering them). So, with all due respect, all I want to know is about the small arms training.
