Which General Order emphasizes keeping alert while on duty?

The General Order that emphasizes keeping alert while on duty is indeed General Order 2.

Being alert is crucial for ensuring the safety and security of personnel, equipment, and sensitive information. It reminds service members to always be prepared to respond to any potential threats or situations that may arise while they are performing their duties.

The other General Orders address different aspects of conduct and responsibilities while on duty.
