Youngsters swapped their school uniforms for military attire to take part in special Army assault courses.
And children at Lee Brigg Infant School showed they had plenty of discipline during the fundraiser in their playground and school fields.
Pupils crawled, ran and jumped their way through obstacles during a day of activities last Tuesday.
Games included dodgeball, dance and the assault course, which was run by Jamie Price and his team from Next-Gen Sports Coaching.
All of the school took part, including some of the teachers, with youngsters getting sponsorship from family and friends so they could avoid usual lessons.
Headteacher Linsey Cavell said the day was a great success.
Miss Cavell added: “The children thoroughly enjoyed working with Jamie and his team.
“They enjoy raising money for school funds.
“They all worked very hard on improving their fitness.
“We are still counting up how much was raised from the day, but I am sure it will go a long way to helping improve our sports provisions.”
Money raised from the Army Themed Sportathon Fundraiser will go towards new gym mats, which help make the school hall safer.
During last week’s activities, special awards were also given out to the fastest boy and girl through the assault course.
And youngsters Lily Sanderson and Luis Scholey-Marsh, pictured right, showed off their nimble skills while the Express photographer was taking pictures at the village school last Tuesday.
Their fellow pupils Jensen Morris and Ciaran McWilliam were a dab hand at throwing a ball through a net.
But the giggles were too much to bare for Jenson as he saw the funny side to playing dodgeball.
