Jointness was a term coined by the US armed forces to describe inter service cooperation.
- It’s a combination of at least two arms in the military coordinated towards one common goal. In the US, there is a direct linkage between the term jointness and theatre command. They are used in a synonymous manner.
- However, in UK, a theatre refers to a geographical area of operations for which if the situations so demands, a competent commander is assigned specific responsibility and provided with joint forces.
