The 500,000th matchday ticket has been distributed to Tickets For Troops with Latics contributing to a small percentage of that overall figure.
Lance Corporal Louize Watson of 22 Signal Regiment was presented with the 500,000th ticket by Prime Minister David Cameron and England Football Manager Roy Hodgson at St George's Park last week.
Prime Minister David Cameron has supported Tickets For Troops from day one and was pleased to help mark the celebrations.
He said "I'd like to congratulate Tickets for Troops on reaching such an impressive milestone. Our Armed Forces make sacrifices every day to keep us safe and we have a duty to ensure we are doing all we can for them in return.
"That is why the Government has set up the Armed Forces Covenant to encourage businesses, local authorities and communities to give something back to our troops.
"This scheme is exactly the kind of thing we want to encourage and is a wonderful way to recognise these brave servicemen and women."
Last season, Oldham Athletic contributed over 400 tickets to Tickets For Troops and the club will continue to support the charity in the coming years.
