The @Martian Congressional Republic (MCR) maintains several intelligence and security organizations responsible for foreign espionage, counterintelligence, military security, and the protection of strategic infrastructure.
Surveillance on @Mars is less commercially pervasive than @Terran monitoring but more closely integrated with public institutions. Service records, professional evaluations, security clearances, and civic assessments provide the government with detailed information about its citizens.
Dissent is not automatically treated as treason. Criticism of officials and policies is common within approved political channels. Activities believed to threaten planetary infrastructure, military readiness, or the Great Project are treated far more severely.
Martian intelligence services are known for methodical planning, patient infiltration, and carefully controlled operations. They prefer precise intervention over large-scale disruption.
Their greatest fear is not public disagreement. It is an unknown vulnerability within a system upon which an entire planet depends.
