Synchronization can involve any data.

   A sends "Attack at 5:00, send your plan"
   B sends "Attack at 5:00, send your plan"
   A sends "Attack at 5:00, send your plan"
   B sends "Attack at 5:00, send your plan"
   A sends "Attack at 5:00, send your plan"
   B sends "Attack at 5:00, send your plan"
Repeat until you got 3-4 confirmations of same data being sent back to you and the plan will work.

Is it 3 or 4? Is 2 enough?

Let’s say the last message in your example is dropped

B would have 3 acks from A while A only has 2 acks from B.

Will A attack? If not, B is left attacking on their own.

Similarly, what if none of Bs messages make it back to A? How does B know to attack?
