MYSTERY
I am 12, right and left makes me 24
10 of us in each side are brothers in arm
The 1st of us is the strongest of them all
The last 2 of us thinks that they are great swimmers
We serve and protect
But sometimes cause problems if accidentally whacked
What are we?

This one very familiar........ but cannot remember.
Let me recall.....
