This figure outlines the procedure to plan an operation and its structure in Defense and Security.

The operations root force element allows the planner to aggregate all the operations plans under one parent or by planning authority, so they are easily identified and accessed. You can use this to separate contingency plans (that is, tentative operations plans) from real on-going operations.
This is different from the unit that is responsible for that operation and serves as the commanding headquarters. This separation is performed by A/B 002 and 822 links.

The operation is represented by a force element, that is technically the same object that was covered in the earlier units.
The validity dates are of the Operation's object itself, and are different from the start and end date of the operation itself. Notice that while the validity dates are mandatory during the creation of the operation's header, the operational period, that is, the actual start and (predicted) date of the operation are optional at this point. A good practice is to keep the validity dates range wider than the expected operational period, to allow more flexibility.
Some of the standard facts are not applicable to the operation's header and thus cannot be edited. Instead, the planner has to define some unique operation data. This are used for reporting and analytics.

Notice that the start and end date of the operation are different from the start and end date of the Operation Force Element itself:
- The start and end date of the operation itself may be unknown during the planning (for example, a contingency plan)
- When the plan becomes concrete, the planner can assign the start date, and speculate what the end date will be.
The climate, terrain, and weather attribute can support the planning in the process of defining the right equipment and the correct type and quantities of provisions to support the mission.

When the operation is created, the planner can start defining the operational Force Elements. Operational Force Elements are special entities that exist only for the operation, and come on top of the standard structure:
- You cannot aggregate the number of operational Infantry BN Force Elements and add them to the number of real infantry BN in your organization.
- When you are assigning a real unit to an operation it is not duplicated and only gets additional 823 links.
The level of details in which the operational Force Elements are defined is related to the actual resources assignment intent.
- If the intent is to assign a complete organic unit, it is enough to define a high-level operational force element that will serve as a framework (for example, a patrol boat, Infantry company, and so on).
- If the intent is to use a standard type of unit (that is, light infantry company) but choose and assign individuals (and equipment) from different organic units to the operation, a detailed force element and structure are required. Such Force Elements and structures can be created manually, or by coping from a regular or reference force element.
- If the operation requires a specific and unique force structure, it has to be manually created down to the lowest level, similar to creating a standard force element.
- An Augmentation: in case a standard type of unit has to be augmented by a special task force (for example, a K9 Team), it could be enough to keep the standard unit as a 'framework' force element, and add a detailed force element and structure only for that augmentation.
Creating an operational force element is almost identical to creating a regular force element and it has the same set of facets. You can define the readiness level, capabilities, METLs, addresses, authorized equipment, controlling and finance attributes, and so on.
