The PrepOS™- Critical Injury Response Framework (M.A.R.C.H) is a prioritized medical response framework used to address life-threatening conditions in the most critically correct order.
 
 
Order of Operations
Treat what kills first. M.A.R.C.H. prioritizes the most immediate threats to life—because in critical moments, sequence is survival.
 
Continuous Reassessment
This is not a checklist—it’s a cycle. Assess, treat, reassess, and repeat. Conditions change fast, and your response must keep pace.
 
Application
Built for high-risk, real-world environments—adaptable from tactical settings to civilian emergencies where structured, decisive care saves lives.
