Addressing an email to an Army officer requires the same etiquette you would extend to any professional contact. But keep in mind rank and professional designations when addressing the officer, and understand that the task will involve some additional time and security considerations not typical of other forms of professional email.

E-Mailing an Army Officer

Connect to the Internet with your computer

Connect to the Internet with your computer and open your email application (or navigate to your web-based email client).


Type the officer's email address in the "to" field above the body of your email. All Army addresses end in "army.mil," but can vary based on division or location (such as "mepscom.army.mil" or "us.army.mil"). The service's email template–firstname.lastname@us.army.mil–may help you guess an officer's email address, though there are several variations including firstname.lastname@goarmy.com for recruiting officers.

Address the officer

Address the officer by name in the greeting of the email. In professional or formal correspondence, you should always use the full title of the officer's rank (example: Dear Lieutenant Colonel Smith). Do not abbreviate rank.

Use the officer's

Use the officer's rank instead of his professional prefix if the officer has obtained both. Instead of "Doctor Smith," address the officer as "Colonel Smith."

Type a clear and definitive subject in the subject line. Write factually and directly to the officer in the body of the email. Military personnel appreciate polite but succinct communication.

Things Needed

  • ['Computer', 'Internet connection', 'Email application', "Recipient's name, rank and email address"]


  • If an officer is deployed, she may be in a different time zone and involved in combat. Consider this when awaiting a reply, requesting immediate attention or writing an email of length.

    Due to security concerns, emails with attachments may not successfully reach a military address. Instead, reference the information and ask the officer if he is able to accept the proposed attachment.


  • The military monitors correspondence sent to an official Army email address for security purposes. Do not include any words that might be flagged, even in jest. Do not include links or references to any illegal activity.
