In 'The Mercenaries: Operation Mad Jackal', you can play as three different UBCS members, each with a distinct playstyle:

- Mikhail Victor: Starts with a powerful Shotgun and Grenade Launcher. Best for direct combat and clearing groups. His slow movement makes dodging difficult, so rely on brute force.
- Nicholai Ginovaef: Equipped with a Handgun and Knife. His strength lies in his speed and ability to earn bonus time for knife kills. Requires precise aiming and risk-taking.
- Carlos Oliveira: Starts with an Assault Rifle and First Aid Spray. A balanced character, good for both offense and defense. His assault rifle is excellent for sustained damage.
Each character requires a different strategy to achieve high scores. Experiment with their loadouts and learn the optimal routes for each to maximize your score and unlock rewards.
