A list of Port Adelaide and Geelong players who have served in conflicts around the world will be displayed prior to Saturday night's game at the Adelaide Oval.
In all, 182 Cats players have served time in times of conflict, from the Boer War through to Vietnam.
Of them, 110 served overseas, 13 were killed in action and six received bravery awards.
More than 60 Geelong players served during the First World War, nine of whom gave their lives for their country during that conflict.
Four of those men died at Gallipoli.
Among them was Joseph 'Alan' Cordner, who played three games for Geelong and 20 for Collingwood before enlisting.
He landed on the Gallipoli beaches on April 25, 1915, and died that day, aged 24.
Joe Slater was another Geelong player who landed at Gallipoli. Slater survived the carnage in Turkey, then rose to the rank of Captain before being killed in action in France in 1917.
Slater had previously notched 108 games with the Cats between 1906 and 1914.
Regarded as one of the best running players of his time, he was named on the half-back flank in Geelong's Team of the Century.
