<!-- Note Section BEGIN -->
 
Note that this way of removing elements from an array will not work if those elements are themselves arrays.
 
Example:
 
[[0,0,0],[1,1,1],[2,2,2] ] - [1,1,1]
 
Will not remove the element [1,1,1] from the first array.
 
A more practical example:
[ [[getPos]] unit1, [[getPos]] unit2, [[getPos]] unit3] - [[getPos]] unit3
 
Will not remove the position of unit3 from the first array.

This will work if you do: <code>[[3,3,3],[1,1,1],[5,5,5]] - [[1,1,1] ]</code>
You have to cover it in extra brackets, because you want to remove the whole element.
Not: <code>[[3,3,3],[1,1,1],[5,5,5]] - [1,1,1]</code>
But this would work again: <code>[[3,3,3],-1,-1,-1],[5,5,5]] - [1,1,1]</code>
Note, that all elements found will be removed: <code>[1,2,3,2,4,3,5,2,6,2,7,2] - [2] //Return: [1,3,4,5,6,7]</code>
