I made one more upgrade for my metal knees after Mark IV to get larger ones in March 2020. The knees for were slightly too small, so I got bigger ones made and passed the other ones to another Vod that needed knees.
In February 2022 I added rockets to the sides of each knee. It helped differentiate between left and right sides. I used air blow guns/air chucks for the rockets.
I affixed a housing for the rocket darts to sit on, so that they are not just stuck on the side following CRLs for weapon mounted systems.
I added some padding foam to the back side of each knee to help me when I kneel on concrete. Towering over 6ft can be intimating to children, so I like to kneel down to their height while trooping.
I later removed the padding as it did not fit aesthetically while in full kit.
