Which of the following is NOT one of the four fires with respect to the target?

Direct fire is typically associated with engaging a target head-on, where the gun is aimed directly at the target, which is a common method. However, when discussing the four types of fire in relation to targets, the focus tends to be on more tactical classifications that emphasize angles and the relationship between the target and the firing position.

Frontal fire refers to targeting an enemy straight ahead, while enfilade fire involves shooting along the length of a target formation, which increases the effectiveness of the fire due to the angles involved. Oblique fire pertains to engaging a target at an angle, which can be advantageous in certain scenarios as well.

These types of fire are crucial for understanding tactical advantages, the geometry of weapon positioning, and maximizing impact on the target. In this context, direct fire does not fit the specific categorization scheme being referenced, as it is a more straightforward, conventional method of targeting that does not highlight the tactical advantages associated with the other types of fire listed.
