In XCOM 2, the soldier progression system is a core aspect of the gameplay, allowing players to develop their team members through a structured rank and ability upgrade system. Soldiers begin as Recruits and, through combat experience and mission achievements, can earn promotions that enhance their performance and tactical capabilities.

Soldier Ranks and Promotions
Soldiers advance through a clear hierarchy of ranks:
– Recruit → Squaddie → Corporal → Sergeant → Lieutenant → Captain → Major → Colonel

With each promotion, soldiers not only gain higher ranks but also receive:
1. Class-specific Ability Upgrades: Each class (Ranger, Grenadier, Sharpshooter, Specialist) offers unique abilities that align with their combat roles. The promotion unlocks their skill tree to allow for specialization.
2. Enhanced Statistics: Increases in health, aim, and willpower are granted, enhancing a soldier’s survivability and effectiveness. For example, higher health enables them to endure more damage, while improved aim directly impacts their shooting accuracy.

Ability Customization
The ability upgrade system is based on class-specific skill trees, providing players with the opportunity to customize their soldiers’ abilities to fit specific strategies:
– At Squaddie rank, soldiers receive their first class ability, introducing them to their primary role.
– As they climb the ranks, especially at more advanced levels like Lieutenant, they can select specialized abilities. For instance:
– Conceal: Allows the soldier to re-engage from stealth, adding a layer of tactical depth in ambush scenarios.
– Run and Gun: Enables soldiers to move and still engage in actions, facilitating aggressive playstyles.

Players can choose to follow one specialization path closely or mix abilities from both paths to create hybrid builds that utilize the strengths of each.

War of the Chosen Expansion
The introduction of the War of the Chosen expansion adds another layer of depth to the soldier progression system:
– Ability Points: Soldiers earn Ability Points that grant additional flexibility in skill selection. This means players can choose abilities they may have initially overlooked, fostering diverse tactical options.
– New skill trees, like Battle Medic or Combat Hacker, provide even more avenues for development, allowing soldiers to adapt to changing battlefield dynamics.

Additional Skills from the Training Center
Beyond rank promotions, the Training Center offers a chance for soldiers to unlock bonus skills. These skills are randomly assigned, but they ensure that soldiers can acquire additional capabilities that enhance their versatility and contribute to team strategies. This feature allows for a layer of unpredictability and strategy in dealing with mission challenges.

Conclusion
The detailed soldier progression system in XCOM 2 not only enhances gameplay but also ensures that each mission contributes to the development of your soldiers. Players are encouraged to make strategic choices about rankings and abilities, which can significantly affect their tactical options and overall success in the campaign. Ultimately, the blend of rank promotions, class-specific upgrades, the introduction of the Ability Point system through War of the Chosen, and the random skills from the Training Center fosters a deeply engaging and customizable experience as soldiers evolve based on player decisions throughout their military careers.
