What are the two types of smoke missions in mortar practice?

The two types of smoke missions in mortar practice are Immediate Smoke and Quick Smoke. Immediate Smoke missions are conducted to provide instant obscuration for the purpose of concealing troop movements or operations from the enemy. This type of smoke is typically employed in urgent situations where immediate cover is required to protect friendly forces or to create a tactical advantage during an assault or movement.

Quick Smoke missions, on the other hand, are designed to generate smoke quickly but may not be as time-sensitive as Immediate Smoke. Quick Smoke can be used for operations where there is a need to provide visual coverage or disruption to the enemy but allows for slightly more planning than an Immediate Smoke mission. Both types of smoke missions are crucial for battlefield obscuration, allowing units to operate more safely and effectively in the field.
