Which of the following is a capability of field artillery?

Shifting fires rapidly is a key capability of field artillery. This capability allows artillery units to quickly reposition their fire to target different locations on the battlefield in response to changing tactical situations. The ability to adjust the direction and range of fire provides commanders with the flexibility to engage moving targets, support advancing troops, or suppress enemy positions effectively.

Field artillery systems are designed to quickly receive targeting information and execute fire commands, which is essential in modern combat scenarios where time and precision can significantly impact the outcome of engagements. The mechanisms involved, such as advanced fire control systems and coordination with observers, enhance this capacity, ensuring that artillery can provide timely and accurate support to infantry units and other forces on the ground.

Other capabilities mentioned, such as manning infantry positions, conducting airborne operations, and creating supply routes, do not pertain specifically to the artillery's role on the battlefield and therefore highlight the specialized nature of artillery operations in providing fire support.
