Tips for Using AF Form 1901 Effectively

Follow Protocol — Consult your unit’s protocol office or DAFI/AFI guidance on official invitations and social events. Details like wording, guest addressing, RSVP instructions, and dress code must align with Air Force standards.
Fill Accurately — Use clear, formal language. Include event date, time, location, purpose, and any special instructions.
Printing and Distribution — Print on high-quality cardstock if producing physical copies. The preprinted format is optimized for professional appearance.
Coordination — For events involving a Lieutenant General, coordinate through the appropriate aide-de-camp or executive officer to ensure the invitation accurately represents the host.
Digital Alternatives — In some cases, electronic invitations may supplement or replace physical cards, but formal Lt Gen-level events often still require the traditional preprinted format for prestige.

AF Form 1900: For General (four-star) level invitations
AF Form 1902 and others: For Major General and related ranks
Blank formats (e.g., AF Form 1938) for greater customization when preprinted options are insufficient

These forms support a tiered approach to protocol based on the host’s rank.

In the U.S. Air Force, attention to detail in protocol reflects respect for rank, tradition, and the mission. Using AF Form 1901 correctly helps ensure invitations are received positively, events run smoothly, and the hosting command upholds the highest standards of military professionalism.
