====== Pathfinder Scout Motorcycle (F-2) ======

===== Overview =====

The **Pathfinder** is a military scout motorcycle with sidecar, built around the
**Hydra F-2** flat twin engine. It is designed as a **forward reconnaissance and
escort platform**, capable of operating independently for short durations while
maintaining communication, concealment, and controlled escalation of force.

The Pathfinder is **scout-first by doctrine**, but **military by construction**.
It is not intended to fight sustained engagements, but to observe, persist,
apply pressure, and disengage.

===== Design Philosophy =====

  * Information before destruction
  * Persistence over speed
  * Silence preferred, force available
  * Mechanical solutions over procedural ones
  * Error prevention through physical design

The Pathfinder exists to create **options**: observe unseen, report reliably,
compel surrender when possible, and deny escape when necessary.

===== Powerplant =====

==== Engine ====

  * **Hydra F-2** air-cooled flat twin
  * Operational tune: ~35 HP (undertuned)
  * Optimized for low-RPM torque and reliability
  * Designed for continuous operation under load

The F-2 was selected for its low profile, smooth operation, fuel efficiency,
and ease of field maintenance.

==== Gearbox ====

  * 3 forward gears
  * Reverse
  * **Generator Mode (G)**

Generator Mode is a **true mechanical selector**:
  * Final drive disconnected
  * Generator drive engaged
  * Vehicle cannot move while in G
  * Governor linkage engages automatically

This prevents accidental movement and enforces safe stationary operation.

===== Generator & Electrical System =====

==== On-board Generator ====

  * Engine-driven in G mode
  * ~200 W continuous output
  * ~300 W short-duration peak
  * Sized for sustainment, not tool power

The generator exists to support lighting, communications, and battery charging.
It is not a general-purpose power source.

==== Governor ====

  * Mechanical centrifugal governor
  * Active only in Generator Mode
  * Maintains RPM within a defined band
  * Conserves fuel and stabilizes voltage under load

==== Electrical Architecture ====

  * **13 V Emberstone standard**
  * No universal outlets
  * Task-specific circuits only
  * **Breaker-protected**, not fused

All circuits use **dedicated, keyed connectors** to prevent misconnection.
If it fits, it belongs there.

==== House Batteries ====

  * Two medium batteries in sidecar trunk
  * Wired in parallel (equivalent to one full automotive battery)
  * Balanced left/right for weight
  * Battery selector: A / B / BOTH

Batteries provide peak buffering, silent night operation, and reserve power.

===== Lighting System =====

==== Scout Interior Light Set ====

  * ~5 m low-watt white incandescent light string
  * Parallel or series-parallel wiring
  * Single bulb failure does not disable the string
  * Heavy-gauge, over-spec wiring
  * Safe to operate even if left coiled

Used for interior tent lighting or as a low-intensity area lamp.

==== Dedicated Lighting Lead ====

  * Purpose-built lighting-only cable
  * Same heavy-gauge wire as light string
  * Keyed connector (lighting circuits only)
  * No indicators or illuminated components

Allows all lighting to remain **inside the shelter**, with no visible light
path back to the motorcycle.

===== Communications =====

  * Backpack radio (crew-issued)
  * Vehicle docking provides:
    * External power
    * Slow battery recharge
    * Whip antenna interface
  * Tall spring-base whip antenna with fold-down travel latch

Doctrine emphasizes listening, short transmissions, and battery-buffered bursts.

===== Armament & Mounting =====

==== Front Pintle Mount ====

  * Frame-mounted pintle post
  * Height requires gunner to:
    * Kneel on passenger seat, or
    * Stand on the ground
  * Driver cannot operate the weapon
  * Traverse hard-stops prevent firing into the vehicle

The mount is issued with the vehicle. Weapons are not.

==== Role of Armament ====

The machine gun is intended for:
  * Suppression
  * Denial
  * Intimidation
  * Disabling vehicles
  * Breaking contact

It is not intended for sustained firefights or static defense.

===== Mobility & Fuel =====

  * Typical top speed (loaded): ~70 km/h
  * Light-load top speed: ~90 km/h
  * Designed to keep pace with infantry

==== Fuel Capacity ====

  * Two **20 L steel fuel cans** (German-pattern)
  * Dedicated external mounts
  * Low and outboard placement for stability

Fuel is considered vehicle sustainment, not personal kit.

===== Tactical Employment =====

==== Scout Role ====

  * Forward observation
  * Route reconnaissance
  * Listening posts
  * Shadowing and reporting

==== Escort & Interdiction ====

  * Infantry escort
  * Mobile suppression
  * Pressure at checkpoints
  * Short-duration pursuit

The Pathfinder can apply pressure briefly but cannot outrun cars indefinitely.
Chases exist only while influence exists.

===== Capture Doctrine =====

Preferred outcomes, in order:
  - Compel surrender
  - Disable and capture
  - Eliminate if resistance continues

Targets are enemy officers, couriers, and spies. Information and leverage are
valued over kills, but lethal force is accepted when necessary.

===== Issued Equipment (Vehicle) =====

  * Generator and governor
  * Electrical system and breaker panel
  * House battery mounts and wiring
  * Scout Interior Light Set
  * Dedicated Lighting Lead
  * Tube-cell charging bay
  * Front pintle mount
  * Two 20 L fuel cans
  * Saddlebags, racks, and lash points

===== Not Issued with the Vehicle =====

  * Tent and shelter
  * Bedrolls and personal gear
  * Radio set and accessories
  * Weapons and ammunition
  * Rations and medical kit

These are crew- or mission-issued items.

===== Summary =====

The Pathfinder does not fight battles.
It **shapes them**.

It is quiet when it can be, dangerous when it must be, and never present longer
than necessary.
