Commitment to National Defense: why is it celebrated on December 19?

December 19 is Reservist's Day in Brazil. This date was created to recognize and value citizens who served in the Armed Forces and are now in reserve, but continue to contribute to the defense and security of the country

The celebration of Reservist's Day dates back to Law No. 6,880, of December 9, 1980, which instituted the Military Statute. This legislation establishes guidelines on the reserve and the promotion of respect and recognition for military personnel who have already completed active service. The objective of the date is to highlight the importance of reservists and their ongoing preparation to assist in military operations, if necessary. Reservists are people who, after completing mandatory or voluntary military service, are available to be called up in case of need, such as in emergency situations, crises or war.
