Section 3-1.4 of UFC3-600-1 is for the "Total Water Demand for Sprinklered Occupancies." The total water demand for sprinklered occupancies is equal to the sum of the domestic/industrial demand plus the sprinkler system(s) water demand and the hose stream(s) demand. The total demand must be available at the sprinkler system connection to the underground main, and at the pressure necessary to produce the required sprinkler density over the required hydraulically most remote area of sprinkler operation.
So I would think the "fire flow" portion of this would be the total water demand minus the domestic. Table 4-1 of the UFC will give you the hose stream allowances. I would also recommend finding the appropriate UFC for your facility to see if anything is stated in that document in addition to UFC 3-600-1. They usually just refer back to 3-600-1 but it's not always the case.

I've got the 2006 and it references IBC, but not IFC. A couple of occupancy specific fire flow rates are prescribed, as for refueling facilities and parking areas, but there isn't a table or matrix as we conventionally use.

The question is what reduction you can take for sprinklers. Code says "up to" 75% with approval of the AHJ; obviously, most municipal FD's offer 50%. What NAVFAC or another DOD AHJ will offer is likely subjective and/or project-specific.

Appendix C Section C-1 says "Use the following procedures to determine the required fire flow demand and duration for buildings that are not fully sprinklered." It doesn't say what to use for fully protected or am I missing something?
