After a slow first half, the Royal Navy scored early in the second half through Ciara Boylan.
But they also had Anthea Kaptein – who was already on a yellow card – controversially sent off for hand ball.
Rachel Griffiths struck back for the Air Force to make the final score 1-1.
Thanks to the RAF’s goal against the Army, and the fact that neither the Army, nor the Navy, scored in their match up, the spoils went the way of the Light Blues.
