Which of the following sections are designated by command at an MCI?

In Incident Command System (ICS) for Mass Casualty Incidents (MCI), the four major sections are:

Planning: Collects data and develops response strategies

Logistics: Supplies and personnel

Finance/Administration: Cost tracking, contracts, compensation

Staging is a tactical location, not a management section. Catering and aviation are not command-level ICS designations unless part of specific tasks under logistics or operations.
