The aim of the event is to challenge soldiers' navigation, use of ground and aerobic fitness through orienteering. The Harris event on day two also provides junior leaders the opportunity to test their leadership under the pressures of time and competition.

The Inter-Unit Orienteering Championships 2024 will be conducted in three phases, the first being optional. Coaching is on offer during the morning of Wednesday 22 May, immediately prior to the championships. This will be aimed at those who require an introduction, or refresher. Attendance will not be limited but units must declare their intent to attend when registering.

The second phase is the Spanish Score on Wednesday 22 May. Team members run individually to visit all controls in the fastest possible time. Controls can be visited in any order and the team's time is the cumulative time of every member.

The final phase is the Harris Team on Thursday 23 May. The Harris format is an event where all team members receive identical maps and run simultaneously. There are two sets of controls: `spine` controls, which must be visited by every team member; and `other` controls, which must be visit by at least one team member. Both sets of controls can be visited in any order, and the team`s time is that of the last member to reach the finish, multiplied by four.

Orienteering directly supports dismounted close combat skills by developing soldiers` ability to `read` the terrain and navigate their way through it. The Army Inter Unit Championships presents a competitive environment to test these skills under physical duress and to promote a `warrior ethos` and will to win.
