Unit award

To be awarded the Military William Order a military unit must distinguish itself in battle to such a degree as would warrant the personal presentation of the Military William Order. The unit's Regimental Colour are decorated with the badge of the 4th Class itself, which hangs from the finial of the pike. The version of the Military William Order for unit members is known as the Orange Lanyard. Only those who served in a military unit at the particular time of action are entitled to wear the Orange Lanyard.

The Orange Lanyard is worn as a cord around the right shoulder and can be worn simultaneously with the French or Belgian Fourragère of the Croix de guerre. The Orange Lanyard is considered a permanent decoration and is worn for the duration of a military member's career.

At least three foreign military units received the Military William Order:

The U.S. 82nd Airborne Division for gallantry at Nijmegen, during Operation Market Garden in 1944;
The Polish 1st Independent Parachute Brigade for gallantry at Arnhem, during Operation Market Garden in 1944;
The U.S. 101st Airborne Division
