Is anybody fluent in Czech?

So my brother joined the Army last year and has gone through basic, jump school, and is in special forces selection now. He will have leave in a few months for a week or so, i had mentioned to him that i wanted to get a tattoo to honor him for his service to me, our family, and our country.
He liked the idea but suggested that we get similar tattoo's. We are of czech descent and i found a picture of the Czech Coat of Arms, i talked to him about it and got him a copy of the picture he liked it and are going to get the tattoo when he is on leave.

Now to my question we where thinking about having "A brothers love" or "Brothers in Arms" spelled in czech put into our tattoo. I have found several different spelling variations for each phrase on different translation website's. We dont want to be those dumbasses that have a mispelled tattoo so can anybody help me out please?

 

I'm one country to the left sorry...

I know there's a translator on google, not sure if it does czech

 

A brothers love = JEDEN bratři Amor

Brothers in Arms = Bratři ve zbrani

Now I pulled this from an online translator.......not sure if it's totally accurate.

 

I pulled some of those also but the problem i was running into was different words in czech from one translator to another.
