Which helicopter is known for its primary mission being troop transport rather than medical evacuation?

The AH-64E Apache is designed primarily for attack missions, including providing close air support and conducting reconnaissance. Its configuration is heavily focused on armament, advanced targeting systems, and combat capabilities. While it can transport personnel, its main function is not troop transport; it's more about engaging in combat scenarios.

In contrast, the CH-53 is a heavy lift helicopter primarily used for transporting troops, cargo, and equipment. The LUH-72A, as a light utility helicopter, is also designed for various roles, including troop transport and law enforcement. The Bell 206 is often used for utility tasks, including transport, but it doesn't have the same heavy lift capacity as some of the others.

Therefore, the distinction lies in the primary operational purpose and capabilities, which reinforces the choice of the AH-64E Apache for its combat role rather than troop transport.
