What element suppresses the enemy on the objective using direct and indirect fires?

The element that is responsible for suppressing the enemy on the objective using both direct and indirect fires is support. In military operations, the support element typically provides the necessary firepower to reduce the enemy's ability to fight while friendly forces advance or maneuver toward the objective. This can include the use of machine guns, mortars, artillery, and other weapon systems that deliver firepower to keep the enemy suppressed.

Support plays a critical role in establishing dominance over the battlefield, allowing other elements such as the assault or maneuver forces to operate more effectively. By utilizing direct fire (weapons fired at a target directly) and indirect fire (weapons that do not require a direct line of sight to the target), the support element can limit the enemy's options and create opportunities for friendly troops to move forward without taking significant casualties.

In the context of the options provided, while defense involves holding a position and preventing an enemy attack, and assault and maneuver pertain to moving against the enemy to achieve objectives, it is the support element that ensures that the enemy is effectively suppressed, allowing other operations to proceed.
