When alerted for a PSO, the individual and collective combat tasks required for mission accomplishment are added to PSO-specific tasks to form a comprehensive task list for predeployment training. Soldiers and units must already be trained on many of these combat and PSO tasks and should only require a review. However, they must train for other tasks more intensely. Training continues in-country if the deployed force is large enough that small units can rotate from PSO requirements to combat training lanes. In Bosnia, collective combat training was practical up to platoon level, to include pregunnery and live-fire training for ground units.
Training areas are available.
Ammunition and other training resources are moved forward. Units can rotate from PSO tasks to training sites. Force-protection conditions are met. Political conditions allow. Conditions usually support the execution of some level of collective combat training.
