What you see here is a lens that focuses the IR light and extends the range of the IR Cannon. How would the clubs you belong to, look at this????.
If these lenses were used on Tigers and Panthers it would allow them to have an effective range that was greater then the Shermans and be more prototypical. THis would mean differnet strategies involved in battle. i.e a Sherman's wouldn't want to battle Tigers in wide open spaces, and instead want to draw them into confined vision spaces.
So what do your club rules say about this? Would the extended range cannon be frowned upon if used on Tigers and Firefly Shermans???
