Military deployment for domestic immigration enforcement raises significant constitutional concerns. Separation of powers (5): Direct use of military for civilian law enforcement violates Posse Comitatus Act principles and blurs military-civilian boundaries. Rule of law (4): Circumvents traditional law enforcement channels and immigration court processes. Civil rights (3): Broad population impact with potential for rights violations during enforcement. Mechanism modifier 1.4 for resource_reallocation redirecting military assets to domestic enforcement. Scope modifier 1.3 for federal action with broad population impact. Severity: High precedent (1.3) for normalizing military in domestic affairs, moderate durability (1.2) as deployments can be sustained, good reversibility (0.9) as troops can be withdrawn. B-score elevated by high media attention (9), strong outrage potential (8), and pattern matching (8) to historical concerns about military domestic use. Delta of +7.4 clearly places this as List A.
