Someone on here will certainly know more, but I think the FC Battalion has been disbanded as a staffed unit. Used to be assigned on the second alarm but I haven't seen that happen in a long time. Of note, the SFAD for Field Comm and the FC Batt would be different things - SFAD is someone with the rank of Supervising Fire Alarm Dispatcher, while the FC Batt would have been staffed by an operational battalion chief, I believe. Different training, different roles. I also believe that 16G, when assigned, responds to a dispatch centre and not to the scene of an incident. Again, just my understanding, others will know more.
