What additional information can be sent along with the MTO?

The correct choice encompasses all options listed, indicating that multiple types of additional information can be sent along with the MTO, or Mission Type Order.

Probable Error in Range provides useful data regarding the accuracy of the firing solution, helping to assess how far the projectiles may deviate from the intended target due to various factors. Including this information can be crucial for adjusting fire and ensuring that rounds impact as close to the desired point as possible.

Angle T, which refers to the target angle relative to the firing unit's position, can assist in understanding how fire may need to be adjusted based on topography and landscape features. It is important for coordinating artillery fire effectively, particularly in complex terrains.

The PRF Code, or Precision Guided Munitions (PGM) code, is vital when employing precision-guided munitions as it identifies the specific munitions and adjustment settings needed for precision targets. This information ensures that appropriate munitions are used for the intended mission and that they are guided accurately to the target.

Therefore, all these pieces of information support the effectiveness and accuracy of artillery operations, enabling a comprehensive approach to mission execution.
