During the Second World War, the Royal Netherlands Motorized Infantry Brigade, later known as the Princess Irene Brigade was a Dutch military unit initially formed from approximately 1,500 troops, including a small group guarding German prisoners-of-war, who arrived in the United Kingdom in May 1940 following the collapse of the Netherlands. Elements of this force became the nucleus of what was originally called the "Dutch Legion."

The Royal Netherlands East Indies Army was the military force maintained by the Kingdom of the Netherlands in its colony of the Dutch East Indies, in areas that are now part of Indonesia. The KNIL's air arm was the Royal Netherlands East Indies Army Air Force. Elements of the Royal Netherlands Navy and Government Navy were also stationed in the Netherlands East Indies.
