1. Units stats in Hearts of Iron 2
Division: The division is the fundamental unit in Hearts of Iron 2. It represents a group of several thousand soldiers and serves as the building block of your armies. Divisions have various stats that determine their combat effectiveness.
Organization: Organization measures the cohesion and readiness of a division. Higher organization means the division can withstand more damage and continue fighting effectively. It influences a division's ability to maintain a front line and withstand enemy attacks.
Strength: Strength indicates the number of soldiers in a division. The higher strength allows for more effective attacks and defense. It determines the division's capacity to absorb losses and continue to function.
Experience: Experience represents the level of training and combat expertise of a division. Experienced divisions perform better in battle and gain bonuses to their combat stats. Experience is gained through combat, and veteran divisions are more effective than inexperienced ones.
Morale: Morale reflects the overall morale and fighting spirit of a division. High morale boosts a division's combat effectiveness, while low morale can lead to decreased performance and even surrender. Events, leadership, and combat outcomes can influence morale.
Leadership: Leadership represents the quality and skill of the division's commanding officer. Higher leadership improves the division's combat abilities and may grant additional bonuses. Skillful commanders can provide advantages in combat and increase the division's overall effectiveness.
Combat Width: Combat width determines how many divisions can participate in a battle simultaneously. Each battle has a limited width, and divisions with a higher combat width will have a greater impact in combat. It is important to balance the number of divisions and combat width to maximize combat efficiency.
Speed: Speed indicates how quickly a division can move across the map. Divisions with higher speed can outmaneuver slower units, making them valuable for encirclements, flanking maneuvers, and strategic mobility. Speed is particularly important for armored and mechanized divisions.
Strength Types: Divisions can specialize in different types of combat, such as infantry, armor, artillery, or air support. Each strength type excels in specific situations and has unique strengths and weaknesses. Infantry is effective in defensive operations, armor provides offensive power, artillery supports attacks, and air support improves combat outcomes.
Technology: Technological advancements play a crucial role in unit performance. Researching new technologies improves the capabilities of divisions, including better weapons, equipment, and support. Technological superiority can give a significant advantage in battles and overall military operations.
Supply: Units require adequate supply to function effectively. Supply lines must be established and maintained to ensure divisions have access to fuel, ammunition, and other essential resources. Insufficient supply can lead to reduced combat effectiveness, attrition, and even the inability to sustain operations.
Terrain: The terrain on which a battle takes place affects unit performance. Divisions may have bonuses or penalties depending on whether they are fighting in forests, mountains, plains, or urban areas. Understanding and exploiting terrain advantages is crucial for success in battles and campaigns.
Air Support: Divisions can benefit from air support provided by aircraft. Close air support can soften enemy defenses and provide an advantage in combat. Coordination between ground units and air forces is vital for maximizing the effectiveness of both and gaining air superiority.
These detailed unit stats in Hearts of Iron 2 allow players to carefully manage their divisions, considering their strengths, weaknesses, and overall strategic goals. Balancing these stats and utilizing them effectively in battles and campaigns are key to achieving success in the game
