Field post office

It is a place to which mail intended for military units in the field is sent to be sorted and forwarded.

[2] Military post offices abroad strive to provide the same services found in their home country.

Today, military personnel who handle mail must be authorized and trained to do so in accordance with Postal Service and Department of Defense regulations (US).

Working in a war zone and screening for hazardous contents in parcels can be dangerous, but the work does help with positive effect the mail has on morale as well as providing a vital service for the military.

Field Post Offices have special cancellations and their mail is eagerly collected by philatelists, but the cancellations are sometimes anonymised so that the place of posting is not revealed which presents collectors with a challenge.
