Comms discipline is one of those things that takes almost no skill to get right, and costs you enormously when you get it wrong.
The basics: call contacts when you see them. Report status changes. Say when you are breaking off, when you are re-engaging, when you are taking damage, when you are down. These are not complicated requirements — they are just habits that need to be built.
The failure modes are predictable. People either say too little — going completely quiet during an engagement until something has already gone badly — or too much, filling the channel with noise that makes it impossible to extract useful information. Neither is helpful.
The discipline VYPR works toward is concise and timely. You do not need to narrate everything. You need to signal the things that change the picture for the rest of the op. Contact spotted at bearing X. Engaging. Down to low shields. Breaking off north. Back in position. That is enough. That is what your teammates need to stay coordinated.
For longer operations, it also helps to establish a simple structure before the op starts. Who calls contacts? Who controls engagement? Who has authority to call a retreat? Knowing these things in advance means you are not working them out mid-fight when the comms channel is already busy.
If you join an op and you are not sure what the comms setup is, ask at the start. It is a better question to ask then than to find out the hard way during contact.
