During enemy preparatory bombardment, what is the recommended action for soldiers?

Maintaining surveillance while taking cover during an enemy preparatory bombardment is essential for several reasons. This approach allows soldiers to stay informed about the enemy's movements and tactics while minimizing exposure to danger. Staying under cover helps protect against shrapnel and direct fire, which are significant threats during bombardments. By observing the enemy's actions, soldiers can gather critical intelligence on the timing and intensity of assaults, enabling informed decision-making about subsequent actions.

In contrast, advancing toward the enemy during bombardment would increase the risk of casualties due to the ongoing fire. Calling for air support might not be effective or timely, as conditions during a bombardment may limit the availability of air assets or the safety of those on the ground. Establishing a defensive line can be crucial in preparation for an assault, but during bombardment, the focus should be on maintaining safety and gathering information rather than setting static defensive positions that could become compromised.
