How to find out the rank of an opponent in CS GO in competitive mode (MM)

 Sometimes you want to know the rank of the player who is playing against you or with you, but you don’t want to disturb / don’t know how to ask a question / religion doesn’t allow you to ask.

Using this method, you can only find out the rank of the person who has the clan tag.

For this:

1.  Go to the player's steam profile
2.  We join the same group that is in the clan tag.
3. While you are dead, go to the server.
4. Profit! You can see the rank of the person with the same clan tag.

Plus, below are all the ranks in Competitive Mode.
