Kalran: Tales of the four nations/Damage and armor types

Basic damage and armor system
In Kalran: Tales of the four nations three types of units exist, Infantry, Armor, and Air, that shares five armor types, Skirmisher, Light, Medium, Heavy, and Superheavy. With three corresponding weapon type, Gun, Autocannon, and Cannon, with five types of weapon damage, rending, gun, autocannon, cannon, and piercing, with a basic counter system. But damage can't go below one unless that weapon cant target said unit.

Counter system
The first is a counter system based around the three unit types and the three weapon types; With Gun unable to damage Armor, since they lack the power to actually penetrate. Cannon unable to damage Infantry, since infantry are nimble enough to dodge. And Autocannon able to hit both types, but deals lesser damage compared to both. Aircrafts on the other hand can be targeted by all three but said weapon types need to be able to hit flying units

Damage is done by a simple equation.

Skirmishers and Superheavy units are unique here.

Skirmisher units can move through any terrain, while aircrafts are invisible on radar, while firing weapons, even off-axis, with accuracy. But vehicles takes triple damage if flanked, quadruple when hit in the rear, aircraft can be hit by some ground weapons, and infantry immediately goes to pinned when supressed, all takes double damage from Light and triple damage from Rending.

Superheavy units reduces all non Piercing and non Heavy damages by half, unless flanked in which they take normal damage, while infantry are immune to suppression, instead being heavily slowed and having their vision reduced. But vehicles are unable to move through dense terrain, while infantry are heavily slowed, aircrafts are visible on map when near a unit, and Piercing weapons deals doubled damage alongside ignoring the reduction. Stacks with heavy armor and/or shield.

Damage
Damage is calculated easily. With the base damage being times by rate of fire and then deducted by armor and tags.

Infantry
Most infantry comes in squad sizes, where its cheaper to reinforce then replace them most of the time, while their small size allows them to garrison, use cover, move through and are hidden in dense terrain, immune anti-tank weaponry, can hide/ambush, and capture POWs. But in turn they can be supressed/pinned, vulnerable to morale damage, and are easily killed by area of effect weapons. They also have directionality similar to vehicles, taking more damage when shot at the side and the rear, but they will always turn to face their enemy, meaning it requires two units to attack at an infantries flanks/rear, with a minor exception to a first attack out of stealth.

Vehicle
Vehicles are significantly tougher then infantry and immune to small arms but are unable garrison or reinforce, and takes more damage to the sides and particularly the rear, and most have their vision range is shorter than their attack range, and are close to blind when it comes to their sides and rear, necessitating infantry to act as spotters and guard their flanks and rears. And can also suffer from critical damages, from damaged engines to a busted gun.

Aircraft
Aircrafts are more frail compared to vehicles but they can fly, allowing them to avoid most weapons.

Critical damage
A unique type of damage only inflicted to vehicles and aircrafts. Critical damages incapacitates to crippling a vehicle, and if done well can turn the tide of battle.

Whether a vehicle gets damage there is a small chance, which increases when hitting the rear, that damage is a critical, which can be temporary to permanent until repaired. But some weapons and abilities, like the Defenders LAW, can cause a guaranteed type of critical.

Temporary
Stunned crew: Vehicle is briefly stunned

Stunned commander: Vehicle is briefly debuffed

Jammed tracks/legs: vehicle is temporarily immobilized

Jammed weapons: vehicle can't attack

Permanent
These damages will stay until repaired

Damaged autoloader: Vehicle rate of fire drastically decreases

Damaged engines/leg: Vehicle drastically slows down

Damaged tracks/hoverdrive/legs: Vehicle becomes immobilized, if critical hoverdrive over the sea vehicle will sink

Damaged turret: Vehicle must now turn itself to fire at enemy

Damaged gun: Vehicle can't attack

Killed crew: Vehicle crew dies but vehicle remains somewhat intact, allowing commander or opponent to take it, but its heavily damaged most of the time. Aircrafts can't get this damage

Killed gunner: Vehicle can't attack

Killed loader: Vehicle rate of fire decreases

Sub-system
A unique mechanic, limited to epic units and a few special units, is the sub-system.

These units are unique in that they are large/complex enough that each specific system, from the armaments to the engine, can be individually targeted. Compared to critical these individual modules are harder to destroy but doing so will lead to the unit losing any function linked to it until its repaired, ranging from being unable to fire that specific weapon to becoming immobilized. And all of the modules must be destroyed to kill these units, with a few exceptions.
