I couldn't say if they are in sync. When we have events that we need to coordinate, they are definitely in sync. I'm talking about the ongoing SOPs for us, but I would imagine that these are discussed as well through the MSP office meetings. If there's any divergence, corrections would be brought at that level.
As for the other types of members, we have ones who are assigned for a shift, a couple of shifts, or a specific event. Before the beginning of their shifts, these members will be briefed accordingly, depending on the nature of the duties they have to accomplish. They won't necessarily go through all the SOPs, but they will be briefed on expectations during the event.
