Tactical Signs (DV-101)¶
SARmission v3.10+ supports the twelve operationally most important tactical-sign symbols per DV-101 — Germany's federal civil-protection standard for cross-organization situation-picture symbology, used by fire, police, EMS, technical relief (THW), and all aid organizations.
Why this matters for non-K9 BOS personnel
DV-101 is the multi-agency lingua franca for tactical-map communication. A fire-department incident-command operator understands the blue pennant just as a Red-Cross paramedic or a police dispatcher does. SARmission brings this symbology into the K9 mission map — without IC having to invent ad-hoc symbols.
The 12 symbols¶
| Symbol | Category | Meaning |
|---|---|---|
🟥 Red diamond with ? |
Damage situation | Missing person |
| 🟢 Green diamond with ✓ | Damage situation | Missing person (found) |
| 🟥 Red diamond with bandage | Damage situation | Injured person |
| ⬛ Black diamond with ✕ | Damage situation | Deceased person |
| 🟦 Blue pennant with "IPP" | Own forces | IPP / Last-Known-Point |
| 🟦 Blue pennant dashed with "B" | Own forces | Staging area (Bereitstellungsraum) |
| 🟦 Blue pennant with dog symbol | Own forces | K9 unit (location of working dog team) |
| 🟦 Blue pennant with "ELW" | Own forces | Incident command vehicle |
| ⬜ White square with red cross | Measure | Aid station / first-aid post |
| 🟧 Orange pennant | Measure | Collection / supply point |
| 🔺 Yellow triangle with ⚠ | Hazard | General hazard |
| 🔺 Yellow triangle with flame | Hazard | Fire |
DV-101 base-form convention¶
All DV-101 symbols follow these primitives:
- Damage situation → red diamond (square on point)
- Own forces / Measure → blue pennant (rectangle with point on top)
- Hazard → yellow triangle
- Medical measure → white square with red cross
- Deceased / final state → black variant of damage symbol
Setting a tactical sign in SARmission¶
- Click in the action bar on Tactical Sign
- The picker opens with all 12 symbols, organized by category

- (Optional) Add a free-text label (e.g., "LKP at parking lot, 14:00 hrs")
- Click on the map at the desired position — the symbol appears immediately
Persistence¶
- Live-sync stable — symbols sync via Yjs CRDT to all connected peer devices
- Saved into the
.rhsmission file - Included in KML export (with
<styleUrl>for each of the 12 predefined symbols) - Embedded into the printed situation report (PDF)
- Audit-trailed in the mission journal for every add/move/delete
Practical recommendations¶
