A warrant officer II is a senior NCO rank in the British Army and his badge of rank is worn on the cuff and consists of a crown inside a pair of laurel leaves.

The King’s crown instantly identifies this example as dating to before 1952:

The red cloth insert is unusual and I am not sure of its significance. On the rear of this badge is a brass plate, shaped to match the badge which helps support it and a pair of split rings to hold the badge firmly to the sleeve:

The lugs of the badge would pass through the sleeve, with the brass backing panel being worn inside the sleeve and the two rings then pass through the loops to hold everything together.
