During a quick smoke Call for Fire (CFF) using shell smoke (HC), you use HE in adjustment until which bracket is split?

In the context of call for fire (CFF) processes, the decision to switch from high-explosive (HE) rounds to smoke rounds during adjustments is significant for ensuring effective targeting and proper execution of the mission. When executing a quick smoke CFF, using HE in the adjustment phase helps determine the accurate location of the target through visible impacts.

The standard practice is to continue using HE rounds until the 200-meter bracket is split. This is important because splitting the bracket allows for a confirmation that the rounds are landing close to the desired target area before transitioning to smoke for obscuration. At this point, the artillery unit has sufficient information on the target's location, allowing for an effective and safe use of smoke rounds without the risk of obstacles or unintended consequences.

Using 200 meters as the threshold helps ensure the safety and effectiveness of the mission by establishing a clearly defined adjustment before changing payloads. This practice aligns with standard procedures within artillery operations, enabling operators to achieve their objectives efficiently and with minimal confusion on the battlefield.
