How do you use jetpack in stick soldiers 2?

In Stick Soldiers 2, to use the jetpack, first equip it from your inventory. Once equipped, activate the jetpack by pressing the designated button (usually the spacebar or a specific key) to launch into the air. You can control your movement while airborne, allowing you to navigate the battlefield more effectively. Be mindful of your fuel, as it depletes with use and will require a cooldown period before you can use it again.
