In APCO, Association of Public-Safety Communications Officials 10-codes, 10-78 means "Need Assistance" or "Officer Needs Help". It is used by officers, dispatchers, or units to request immediate support due to an emergency, threat, or dangerous situation, ensuring rapid deployment of additional personnel or resources.

  • Officer: "Dispatch, unit 14, 10-78 at 101 Pine Street, suspect armed and resisting arrest."
  • Dispatch: "10-4, backup units en route, additional units notified for immediate assistance."

Operational Purpose

10-78 is vital for officer safety, rapid incident control, and effective multi-unit response. By reporting the need for assistance promptly, units reduce the risk of injury, prevent escalation of dangerous situations, and allow dispatch to allocate resources efficiently.

  • High-risk traffic stops or arrests
  • Active threats involving weapons or violence
  • Disturbances or crowd control requiring multiple units
  • Medical emergencies where immediate backup is necessary

Rapid response minimizes risk, maintains command structure, and ensures all responders are aware of the critical nature of the call.

Variations And Agency Practices

Some agencies differentiate between non-emergency assistance and urgent 10-78 situations. Local protocols often define the number of units to dispatch, the types of support required, and whether additional specialized units such as SWAT, EMS, or K9 teams should be notified.
