Main Effort. A [commander] states his main effort to direct ‘the concentration of capability or activity in order to bring about a specific outcome’. Main effort is what a [commander] considers, at a particular point in time, to be crucial to the success of his campaign. Main effort is given substance in a variety of ways:
(1) Additional resources may be allocated to the component assigned the main effort.
(2) Other components may be assigned specific tasks to support the main effort either directly or indirectly.
(3) Other steps may be taken, such as the narrowing of boundaries and economy of effort elsewhere, to concentrate fighting power.
(4) And most importantly, cognisant of the [commander]’s main effort and priorities, subordinates use their initiative to take timely and independent decisions and action, in fast-moving and changeable operations, thereby optimising tempo. Subordinate commanders may have their own main effort; each should reinforce the [commander]’s main effort.
