Vehicle defect explanation taken from [Dev Diary #26 - Vehicle Defects]

Defects and Hitpoints

All vehicles have certain thresholds when losing HP that can cause a so-called “defect” to appear. These defects are very similar to injuries in Battle Brothers and have various effects and severity.

At 25% hitpoints lost, a vehicle suffers a light defect. These are usually easy to play around with or wear off quickly. Examples of light defects are a small fire, overloaded controls that stun the vehicle for one turn, or light weapon damage that can cause the attached weapons to malfunction.

At 50% hitpoints lost, a vehicle suffers a medium defect. These are more serious than light defects and can put a huge dent in combat effectiveness. Examples can be a medium fire that keeps damaging the vehicle until it is put out, engine damage that increases movement costs, or damaged optics that reduce view range, detection, and accuracy.

Finally, at 75% hitpoints lost, a heavy defect is suffered. These are always serious and spell the end of a vehicle in many cases. This can be a large fire that quickly destroys a vehicle, or a completely destroyed weapon system or engine, effectively immobilizing a vehicle. A heavy defect can also be a critical hit, instantly evaporating the vehicle in a massive explosion.

There are way more defects in addition to those mentioned above.

Unique Defects

In addition to the generic defects, each vehicle type and even each unique weapon can have defects attached to it.

• EMP Discharge

An EMP weapon can suffer an accidental discharge, effectively stunning all machines around it.

• Flame Leak

Carrying around large fuel tanks is not without risk in a battle zone. A unit equipped with a heavy flamethrower might get its fuel lines punched and leave a trail of fire behind it.

• Rocket Cookoff

A vehicle armed with rockets might shoot off rockets randomly when getting destroyed. Better not be near this one when it blows up!

Known Defects

Light Deffects

Name	Effect/Description	Chance (in %)
Autoloader Jammed	The loading mechanism of the vehicle's weapon is jammed for 1 turn	25
Controls Overloaded	The incoming attack caused a shortcircuit and overloaded the control systems. The vehicle is disabled for 1 turn	20
Cooling Damaged	The cooling systems have been damaged. Heat dissipation is reduced by 1 per turn	30
Crew Shaken	The crew has been shaken by a heavy hit setting their morale to wavering for 1 turn	25
Energy Powerlines Damaged	A small fire broke out on board the vehicle. If not extinguished it does 5% max hitpoint damage per turn	30
Engine Damaged	The engine has been damaged increasing movement costs by 10 AP per tile	30
Knocked Over	The walker has been knocked over and is disabled for 1 turn	25
Light Weapon System Damage	Weapon systems have been lightly damaged giving them a 10% chance to jam. Each use will increase the chance by another 10%. Chances are reset to 10% when jamming	20
File:? Shocked	?	25
Small Fire	A small fire broke out on board the vehicle. If not extinguished it does 5% max hitpoint damage per turn	30
Stabilizers Damaged	The walkers stabilizers are damaged making it more difficult to move. Increases AP costs to move per tile by 10	30
File:? Upgrade Damaged	?	25

Medium Deffects

Name	Effect/Description	Chance (in %)
File:? Accidental Discharge	?	30
Autoloader Damaged	The loading mechanism has been damaged making it a lot less efficient to operate. Any attack skill used by this vehicle costs 50% more AP	30
Crew Injured	The crew has been injured, reducing the vehicles action points by 20	25
Fuel Leak	The damaged tank is leaking fuel leaving behind a trail of fire	30
Mechanics Damaged	The walkers mechanics have been damaged increasing the AP costs for turning to 10 AP	30
Medium Fire	A fire broke out and will destroy the vehicle quickly if it is not extinguished. Does 10% of max hitpoints damage per turn	30
Medium Weapon System Damage	Weapon systems have been damaged giving them a 20% chance to jam. Each use will increase the chance by another 20%. Chances are reset to 20% when jamming	25
Optics Damaged	Optics have been damaged. Vision is reduced by 3, detection by 2 and accuracy by 15%	25
File:? Passengers Hit	?	60
Powerlines Damaged	The energy weapons high power lines are damaged. Every time an energy weapon is used the vehicles receives 5% max hitpoint damage	30
Spalling Damage	The armor has been hit and spalled into the vehicle. It will be a lot less resistant against future attacks. 30% of max durability are instantly lost	20
Steering Damaged	The steering mechanics have been damaged making it hard to maneuver. AP costs to turn are increased by 10	30

Heavy Deffects

Name	Effect/Description	Chance (in %)
