Under martial law, the military takes control of the government and legal system, suspending civilian processes and replacing them with military powers. During this time, the military enforces strict control and regulation over the population, ensuring security and maintaining order. Curfews may be imposed, and freedom of speech, assembly, and movement limited. In extreme cases, martial law can lead to an increase in surveillance and militarization of society, with military personnel patrolling the streets and enforcing law and order. The duration and severity of martial law depend on the specific circumstances and the intentions of those in power, which can vary significantly from one situation to another.
