Background: Search & Rescue with Dogs¶
For first-time readers
This page is for command-staff (ELW) and incident-management personnel from non-K9 BOS organizations who will be working with a K9 SAR team for the first time.
What do K9 SAR teams do?¶
A K9 search-and-rescue team is an operational unit of volunteer dog handlers with certified search dogs. They are typically dispatched by police via the integrated emergency dispatch (ILS in German = integrated control center) when a person is reported missing — e.g. a dementia patient, a lost child, a suicide-risk individual, or a missing hiker.
In Germany, up to 100,000 persons are reported missing each year (BRH 2024 statistics). A subset of these triggers larger search operations involving canine teams alongside police, fire, drones, and other resources.
Who runs K9 SAR teams in Germany?¶
Germany has multiple parallel K9 SAR organizations:
| Organization | Role |
|---|---|
| DRK (German Red Cross) | K9 teams per district association (Kreisverband) |
| JUH (St. John Accident Aid) | K9 teams, often state-level |
| MHD (Order of Malta) | K9 teams |
| ASB (Workers' Samaritan Federation) | K9 teams |
| BRH (Federal Association of Search and Rescue Dogs) | Independent supra-regional association |
| THW (Federal Agency for Technical Relief) | Specialty group "Ortung" (locating) including K9 |
All organizations work to the same tactical principles and are operationally interoperable in the field — including the use of DV-101 tactical-sign symbology.
Search methods¶
| Method | When used | What the dog does |
|---|---|---|
| Mantrailing (MT) | When a scent article from the missing person is available | Follows the specific scent of that one individual — away from the last known location |
| Area Search (FL — Flächensuche) | When the search area is known but no specific scent article exists | Searches a defined area systematically for any human scent |
| Disaster / Rubble Search | After building collapse | Locates persons buried in rubble |
| Water Search | Suspected drowning, missing hiker near water | Detects scent rising from water surface, from a boat |
| Avalanche Search | Skier or hiker buried in snow | Locates persons under several meters of snow |
| Cadaver / HRD Search | Suspected discovery of deceased persons | Specialized scent conditioning |
Roles in operation¶
| Role | Responsibility |
|---|---|
| Incident Commander (EL — Einsatzleiter:in) | Operational control, interface to police/ILS |
| Map Officer (Kartenführer:in) | Maintains the tactical map / situation picture |
| Radio Officer (Funkwart:in) | Receives and sends radio messages |
| Dog Handler (HF — Hundeführer:in) | Works with the search dog in the assigned sector |
| Squad Leader (TF / GF) | Leads a 2–5-person team |
| Platoon Leader (ZF — Zugführer:in) | Leads multiple squads |
Typical operational sequence (7 steps)¶
1. Request → Police/ILS reports missing person to K9 team
2. Mobilize → IC opens a mission, captures victim profile + IPP/LKP
3. Plan → Define search areas, fetch weather, draw Koester rings
4. Resources → Alert own team + other organizations as needed
5. Briefing → Print situation briefing for incoming squads
6. Search → Squads work assigned sectors, report status by radio,
IC enters POD values upon sector completion
7. Closeout → Subject found / search suspended → situation report +
handover to police
SARmission supports every step with dedicated tooling.
Key abbreviations (60-second list)¶
- IPP — Initial Planning Point (where search planning starts)
- LKP — Last-Known-Point (last verified location)
- POA — Probability of Area (likelihood the subject is in an area)
- POD — Probability of Detection (likelihood a search would have found the subject if present)
- Mattson method — Bayes-based prioritization for the next sector
- Koester model — Statistical model of subject behavior (Robert J. Koester, NASAR 2008)
- DV 101 — German federal civil-protection regulation defining standardized tactical-sign symbology
What SARmission is not¶
- Not a dispatch system — it complements ILS/CAD, doesn't replace it
- No automatic resource allocation — squad-to-sector assignment is manual
- No automated radio — radio is handled outside the application
- No ILS / CAD integration in v4.0.0 — roadmap v5.x
