How to effectively use different soldier classes in XCOM 2?

XCOM 2 features several soldier classes, each with its unique strengths and weaknesses. Here are some tips on how to effectively use each class:

1. Ranger - Rangers are excellent at close combat, so you should try to position them near enemies for maximum damage. They can also use the grappling hook to get to high ground, which can give them a tactical advantage.
2. Sharpshooter - Sharpshooters are best used as long-range attackers, and they have a variety of abilities that allow them to take out enemies from a distance. Try to position them in high ground positions for maximum effect.
3. Grenadier - Grenadiers are great at taking out groups of enemies with their explosive abilities. They are also effective at destroying cover, making it easier for other soldiers to take out enemies. Use them to clear the path for your team.
4. Spe******t - Spe******ts have the ability to hack enemy robots and turrets, as well as heal and revive other soldiers. Try to keep them out of harm's way and use them to support the rest of your team.
5. Psi Operative - Psi Operatives have powerful psionic abilities that can be used to control enemies or cause damage. However, they require a lot of training to be effective, so invest time in developing their abilities.

It's also important to consider the synergy between different classes. For example, a Ranger and a Spe******t can work together to clear a path to a hacking objective, while a Sharpshooter and a Grenadier can take out enemies from both long and short range. Experiment with different combinations to find what works best for your playstyle.
