PATROL BOAT
Entry point into the Naval Fleet: a compact coastal patrol platform built around shoreline security, scouting and rapid reaction. Its naval-terrain profile defines the unit: Coastal Waters preserve full stored combat values and much higher movement speed, while Open Sea applies a confirmed −50% attack and −50% defense modifier at every supplied level.

Naval Terrain // Core Mechanic
Open Sea applies −50% Attack and −50% Defense on every
verified Patrol Boat level. This is a terrain modifier,
not a permanent reduction to the stored combat vectors.
Coastal Waters show no matching negative combat modifier.
Open-sea and coastal movement speeds must also remain
separate.
Open Sea Combat
−50% / −50%
Effective ATK and DEF are half of the stored
target-class base values.
Coastal Combat
Full Base Value
No matching negative Coastal Waters combat modifier
is shown in the supplied data.
Coastal Speed
2.63 → 3.75
Coastal movement remains much faster than Open Sea
movement across the full progression.
Attack Range
35 → 50 → 65
Major geometry breakpoints occur at Level 3 and Level 6.

Select Doctrine & Level
All three doctrines use the same supplied combat,
terrain, range, radar, speed, HP and research-day
progression. Doctrine selection changes the verified
class-name progression; level selection updates the
active operational profile.

Combat Vector Rule // Do Not Sum
The ten attack and defense positions preserve the exact
left-to-right icon sequence from the supplied unit data.
The source does not safely provide textual target labels for
every position, so those positions remain unlabeled here.
For calculator use, select the individual value belonging to
the defender’s target class. Never add the complete vector
together into one generic damage number.

Patrol Boat Breakpoints
L1–2
Early Coastal Gunboat
Range remains 35, coastal speed remains 2.63 and
sight remains 40. L2 raises the main naval vector
value from 2 to 2.5 and HP from 10 to 11.
L3
First Major Geometry Upgrade
Attack range reaches 50, radar appears at 50,
sight rises to 45 and coastal speed becomes 3.00.
Additional combat-vector positions also become active.
L4–5
Combat Scaling
Geometry remains stable while the main naval value
rises to 3.5 and then 4. Level 5 raises HP to 14.
L6
Complete Patrol Profile
Main naval ATK/DEF reaches 6, range 65, radar 75,
coastal speed 3.75, HP 15 and sight 50.
Calculator Terrain Rule
Store the base combat vectors unchanged. In Open Sea,
calculate effective target-class attack as base ATK × 0.50
and effective target-class defense as base DEF × 0.50.
In Coastal Waters, use the stored base target-class values.
Open-sea speed and coastal speed remain separate movement
fields because naval terrain changes movement as well as
combat efficiency.
