Dude, the boarding parties of today aren't like they were way back in the Napoleanic war or w/e. You won't be fixing your bayonet and hacking and slashing your way to the enemy's bridge if thats the picture you've got in your mind.Most times the boarding party is used it's for settling disputes between ships and port authorities(i.e. ship doesn't want to pay some fee, boarding party comes in and tells them to figure their **** out,end of story) or to counter smuggling operations in Canadian or Int'l waters.Obviously their purpose is to board and take control of enemy vessels by force, but like many other jobs in the CF, it's quite rare for them to actually fufil their primary role on a regualr basis( with the exeption of SAR techs and CANSOF,among others).
As others have already pointed out to you, you're in a situation right now where you can be shot at( or atleast you will be when your done your trade training and are posted to your ship).If you had problems with this you should have thought of that before you joined up.There are loads of people who would jump at the chance to do a Naval boarding party course, it can be an awesome experience if you apply yourself.
Hell, I'm not even in the Navy and I want to do the Boarding Party course ;D. Do the course.Take it in your stride and get your act together when it comes to "being shot at".Just my :2c: Good luck
