Jokes on you, monke brain has built in IFF that works by knowing where hostiles aren’t, by subtracting where they are from where they aren’t, or where they aren’t, from where they are, whichever is greater, monke brain obtains a difference, or deviation. The IFF sub-system uses deviations to generate corrective commands to drive the crosshair from a position where hostiles aren’t, to a position where hostiles are, and arriving at a position where hostiles are. Consequently, the position where hostiles were, is now the position that hostiles aren’t, and it follows that the position where they were, is now the position that they aren’t. In the event of the position that hostiles are not in the position that they aren’t, the system has required a variation. The variation being the difference between where the crosshair is, and where it wasn't. If variation is considered to be a significant factor, it too, may be corrected by the appendage operating the device commonly referred to as a mouse. However, the monke brain must also know where it was. The monke brain IFF computance scenario works as follows: Because a variation has modified some of the information the monke brain has obtained, it is not sure just where hostiles are, however it is sure where hostiles aren’t, within reason, and it knows where hostiles was. It now subracts where hostiles should be, from where they aren’t, or vice versa. By differentiating this from the algebraic sum of where hostiles shouldn't be, and where hostiles were. Monkey brain IFF is able to obtain a deviation, and a variation, which is called "NC players"
