How does a Military Helicopter work_ 4

Flight Controls: Military helicopters have flight control systems that enable the pilot to maneuver the aircraft. These controls include:

a. Collective Pitch Control: The collective pitch control is a lever located on the left side of the pilot's seat. It adjusts the pitch angle of all the main rotor blades simultaneously, controlling the overall lift produced by the rotor. Raising the collective increases the lift, allowing the helicopter to climb, while lowering it decreases the lift, causing the helicopter to descend.
