An Archangel is an angel of high rank. No, this wasn't decided based on their marks. 

"with the voice of the archangel, and with the trumpet call of God" is a line from a verse in the Bible, we haven't read it yet but we sure would if we saw this on you. 

Don't know about Archangel but, are you our angel? 

(You'd definitely look like one in this.)
