What constitutes difficulties for Target conditions?

The correct choice identifies factors that directly affect the challenges presented when engaging with a target during training or combat scenarios. Range to target, moving targets, and oblique targets all contribute to the complexity of aiming and hitting the target.

Range to target involves how far the shooter is from the target, which can complicate accuracy due to bullet drop and wind impact. Moving targets require a different skill set, as the shooter must anticipate the target's future position while accounting for motion, making engagement more difficult. Oblique targets, positioned at an angle rather than straight on, also add to the difficulty, as they can alter the required trajectory of the projectile and the shooter’s alignment.

The other options focus on characteristics such as target size, color, and material, but these do not primarily define the difficulty in engaging a target as the dynamics of movement and spatial relationships do. While terrain type and visibility may influence overall shooting conditions, they are not specific to target difficulty in the same way as movement and angles.
