Final answer:
Seeking cover is essential when faced with an armed threat and limited/no cover is available. Moving quickly, engaging the threat immediately, and shouting for help are not the best options in such situations. Sun Tzu's 'The Art of War' provides insights into finding refuge and fighting hard when there is no other option.
Step-by-step explanation:
When faced with an armed threat and limited/no cover is available, it is important to remember that seeking cover is essential. It provides a physical barrier that can protect you from gunfire and other dangerous actions. Moving quickly may increase your chances of getting hit, while engaging the threat immediately without cover puts you at a higher risk of harm. Shouting for help is important, but it should not be the priority when your safety is at stake.
The principles of seeking cover in dangerous situations can be seen in Sun Tzu's 'The Art of War.' It emphasizes the importance of finding a place of refuge and fighting hard if there is no other option. It also discusses the use of stratagem and attacking the enemy in unexpected places, which can be applicable to self-defense in certain scenarios.
