Families can explore the cockpit of the last remaining Nimrod in Moray, handle military weapons or enjoy a choral performance on Saturday.
Kinloss Barracks is hosting its annual families day at the playing fields, from 11am to 4pm.
Lord Lieutenant Grenville Johnston will open the event, which has a range of activities for visitors of all ages to enjoy.
Both children and adults will compete against each other on the football pitch, with the RAF taking on the Army in a match at 2pm – after a tournament for youngsters at noon.
Morayvia, a group of volunteers who have preserved the last Nimrod at the former RAF base, will also be attendance, to let visitors look inside the cockpit. There will also be the chance to handle military weapons on display.
Heidi Dunning, of 39 Engineer Regiment, said: “The weather is set to be good so hopefully we will get a good crowd. Everyone is welcome.”
The military wives choir at Kinloss will perform at 12.30pm, when there will also be a mini dog show, with another lined up for 2.30pm.
Youngsters can also enjoy a bouncy castle, face-painting, games and arts and crafts.
There will also be a range of stalls, including one for the RAF benevolent fund team, as well as a tombola and coconut shy.
Entry is free.
