Final answer:
In military protocol, 'Present arms' is typically the command used to initiate a hand salute among the options provided. 'Order arms' is the command to terminate the salute, which is not listed among the options. Following specific branch protocols is crucial for proper salute etiquette.
Step-by-step explanation:
The question refers to the correct protocol for giving a hand salute in a military or cadet setting. When you are at attention and have been given the command to hand salute, the correct command to drop the salute is 'Order arms'. However, among the choices provided in the question, the command that is generally used to initiate a salute is 'Present arms'. When executed, 'Present arms' is the command where a service member would raise their hand to the correct saluting position. The other commands, such as 'Attention', 'Salute arms', or 'Hand salute', are not typically used for terminating the salute. It's important to follow the specific protocol of your unit or service branch as variations can exist.
