Sudden Strike 4 – Doctrines and Skills Guide
Players in Sudden Strike 4 are commanding forces of different factions supported by famous generals through three historical campaigns. Each campaign offers three generals pursuing three different doctrines and skill sets. You can switch between the generals at any time during your campaign without penalty.
• Armoured doctrine
• Infantry doctrine
• Support doctrine
Below is a list of skills that you can unlock over the course of the campaign, depending on your selection of doctrines and your star achievements.
Infantry Drills
Infantry aims more accurately with ballistic weapons.
Hand Grenades
Submachine gunners, riflemen, and paratroopers are equipped with hand grenades.
Piggybacking
Soldiers can get on and travel on any type of tank.
First Aid
Severely wounded infantry can use first aid to recover from a downed state and be able to act again.
Sprint
Increases the movement speed for infantry units.
Grenade Drills
Increases the throwing range of grenades.
Hatch Lookout
More effective use of the top hatch increases the vision range of tanks, but makes the tank commander more vulnerable.
Demolition Kits
Riflemen are equipped with landmines, submachine gunners are equipped with anti-tank grenades or rocket launchers (mission-dependent), and paratroopers are equipped with TNT.
Binoculars
Officer units reveal hidden units in range.
Sandbag Covers
Armored units can deploy a sandbag cover that protects against attacks, but they become immobile.
Armoured Perseverance
Armored unit crew members always survive critical hits to their vehicle.
Repair Kits
Vehicle crews are equipped with repair kits, enabling them to fix critical damage of their vehicles without a repair truck.
Camouflage
Vehicles are more difficult to detect in light vegetation.
Call in the Cavalry!
At the start of the mission, the crew of the strongest armored unit is promoted to elite status.
APCR Rounds
All tanks, self-propelled anti-tank vehicles, towed anti-tank vehicles, recon vehicles and anti-tank infantry deploy with armour-piercing anti- tank rounds.
Top Quality Fuel
Vehicles accelerate faster and receive a slight boost to their turning speed. Maximum speeds are unaffected.
Improvised Armour
Provides extra armour and decreases the chance to receive critical hits for all tanks.
FirePower
Mortars, self-propelled artillery and towed artillery receive a damage bonus when using high explosive ammo rounds.
Army Telemeter
Artillery units fire with more accuracy, decreasing the time to zero in on their target.
Smoke Grenades
Infantry units deploy with smoke grenades. Smoke grenades apply a fog of war effect where thrown, hiding friendly units.
Smoke Discharge Systems
Armored units deploy with smoke dischargers. Smoke dischargers apply a fog of war effect around the unit, hiding friendly units.
Tank Periscopes
Tanks deploy with periscopes, increasing their vision range.
Reinforced Sandbag Bunkers
Towed units can deploy a reinforced sandbag cover that protects against attacks from all directions. The unit can’t be towed while the protection is active.

Infantry units deploy with extra ammunition.
Extinguishers
Armored vehicles are immune to instant fatal explosions caused by critical hits.
Fast Loading
Supply trucks load other units faster.
Army Mechanics
Damaged vehicles can be fixed up to a certain percentage of their maximum hit points by the engineers in repair vehicles. In addition, engineers have the ability to repair critical damage.
Take Cover!
Infantry units’ damage taken in dense vegetation and ruins is reduced.
Perpetuum Mobile
Vehicles become immune to engine failure due to critical hits.
Ramming Speed!
Tanks can ram to cause damage to both themselves and the target vehicle (the vehicle with higher hit points survives ramming).
Quick Reload
Artillery units take less time to reload.
Towing Hooks
Recon vehicles, light tanks, and self-propelled anti-aircraft vehicles can pull towed guns.
Anti-Tank Mine
Infantry units deploy with anti-tank mines.
Backpack
Infantry units deploy with extra gear (Grenades, TNT, AT Grenades, Mines, or Smoke Grenades).
Tough Guy
Infantry units receive damage reduction.
Precision Shots
Decreases the shell dispersion area for artillery units.
Extended Camouflage
Medium / heavy tanks and light vehicles are more difficult to detect in light vegetation.
