I have an idea about this. I do not understand programming, but I think it can be done. Having looked through the forum, I realized that most people talk about a pause of 10 seconds. Maybe you can just set a timer to restrict messages?
Example - Minimum message required for the attack.
/l1 - <Detection of an enemy target. Warning about the readiness of attack> (The attack does not occur. After that, there can be a long RP if both sides want it).
[Programmed Timer Message MSG 10 seconds]
/l2 - <Warning of the attack>. (After this message, the player can open fire).
