Ok, I built a ship with alot of boarding parties...

I didn't explain myself clear enough. I meant that if you are genetically a good soldier with proficiency in hand-to-hand combat(and the percent of ground combat should reflect this) you should also have advantage against weaker foes wherever you choose. Would it be ship, battlegroud, city or anywhere else. Of course you have to recieve a special training but we are talking about boarding parties. These units have surely recieved special training.
