This N4 rule is not used in CodeOne.
Coherency is the game mechanic which allows management of several linked troopers acting together and simultaneously in the same Order while applying a rule, Special Skill, piece of Equipment, Game State... that requires those troopers to stay in close proximity.
Coherency is determined by the Zone of Control of a specific Trooper known as the Reference Trooper. The Reference Trooper can vary and is defined by each rule, Special Skill, piece of Equipment... which requires Coherency (for example, the Team Leader in the Fireteam rule, the Controller of a Peripheral (Synchronized)…).
To be in Coherency, the rest of the linked troopers must be inside the Zone of Control of the Reference Trooper.
Coherency Check
During the Deployment Phase
The player can check Coherency, measuring the Zone of Control of the Reference Trooper to be sure the rest of the linked troopers are inside it.
After having checked Coherency, the player can adjust the placement of those troopers so they are all inside the Zone of Control .
However, this adjustment is not allowed regarding the last figure kept back as reserve, nor during the deployment of that Trooper (or Troopers if any rule, Special Skill, piece of Equipment... allows several to kept back in reserve).
At the start or end of an Order
The player must check Coherency at the start of the Order, after having declared the first Short Skill of the Order, or an Entire Order, or an ARO, but before measuring movement, if any has been declared.
The player must also check Coherency at the end of the Order, at the end of the Conclusion, after having performed any movement due to a failed Guts Roll or any other rule.
Breaking Coherency
When a Coherency Check is failed, if a trooper is out of the Reference Trooper's ZoC, then Coherency is broken and its consequences are applied immediately, as Stated by the rule, Special Skill, piece of Equipment... the player is applying.
In the Active Turn, after declaring a Fireteam's first Short Skill of the Order, or Entire Order, any members out of Coherency with the Team Leader would leave the Fireteam and not be activated. Fireteam Bonuses would then be recalculated.
To make the game faster, in those situations in which it is clear and evident that Coherency is kept (when the troopers are close to the Reference Trooper, and clearly inside his Zone of Control), it is not necessary to perform a Coherency Check, unless the adversary asks for it.
FAQs & Errata
Q: During your main part of the Deployment Phase, can you reposition Troopers, Deployables, etc?
A: Yes, but as soon as you make a Roll, check Coherency, or ZoC, the positions of those Troopers, Deployables etc. are fixed and they cannot be repositioned.
For example, you can reposition a Trooper as many times as you want, but after you create a Fireteam and adjust the placement of the Fireteam members during the Coherency Check, you can no longer reposition any member of that Fireteam.

Q: In the Deployment Phase do you have to check ZoC when a Trooper uses Minelayer, or Coherency when deploying Decoys or Holoechoes?
A: Yes, but your opponent must look away so that you can check the ZoC/Coherency without revealing Private Information.
