Hemel Hempstead school pupils have shown their support for service families by raising £300 with a special red, white and blue non-uniform day.
Chaulden Infants and Juniors Schools invited servicemen and women from the RAF Halton air force station in Bucks to talk to the children about life in the forces.
Pupils were even put through their paces in a drill exercise. The day was part of a national initiative for three forces charities.
School spokesman Julie James said: “We heard about how hard it is with a parent away for a long time and how often children have to change schools. We can’t thank parents enough for their generosity and look forward to supporting these great causes next year.”
