On 16 February 1626, King Gustav II Adolf of Sweden founded the Royal Pori Regiment during the Thirty Years' War.

Infantry Regiment 6 became the peace-time unit garrisoned in Turku after the general demobilisation following the Continuation War.

The Ostrobothnia Jaeger Battalion in Niinisalo trains infantry companies, reconnaissance troops, artillery forward observers and military working dog handlers.

The Niinisalo small animals clinic has national responsibility for the veterinary care of Finnish Defence Forces service dogs.

The Crisis Management Centre is responsible for training and deploying all Finnish Army units in international duties.

For existing operations, the Centre trains new personnel rotations and takes care of domestic human resources management.

The Pori Brigade regularly hosts foreign officials and officers for demonstrations and has a long history of joint training with NATO and other forces.
