“They are in the military. The military has always placed limits on the free speech of its members in order to maintain security, discipline, and espirit de corps. Most importantly, however, there is something troubling, and potentially dangerous to other soldiers, about a group of active duty soldiers meeting on a military base to organize opposition to their own mission.

No. Atrocities are born when soldiers don't speak out against acts of wrongdoing during the war. That's a different thing than attacking the mission and meeting clandestinely (and illegally) to oppose it.
