First-alarm target: 5 fire apparatus, 1 medic, 2 battalion chiefs. Confirmed roster above is 5 fire apparatus / 1 medic / 2 BCs, 20 personnel. Second alarm (struck on command, not shown in this table): Q261, E214, E262, E271 — 4 apparatus, 13 personnel, all Tri-City auto-aid. Once struck, these units appear on the Tri-City Response Map alongside the first alarm.

Dispatch order (who's assigned first) is jurisdictional, not distance-based — but City-boundary GIS confirms Cedar Hill sits directly against both DeSoto and Duncanville along this stretch of Pleasant Run Rd, and DeSoto Station 263 (1301 W Pleasant Run Rd) is genuinely closer by road than several of Cedar Hill's own stations. That's why DeSoto can still show ahead of some CHFD units in the Predicted Arrival Order panel (real drive time) even though it's dispatched after them here (box assignment). Exact parcel-to-boundary distance not computed in this build.

Add new units from the '+ Add On-Demand Unit' control in the roster column (pick a home station there so the unit gets a real map marker). Units already past Dispatched can't be removed here — clear them via normal status/PAR handling instead.
