OP
Observation Post
A position from which military observations are made, or fire directed and adjusted, and which has communication with the command post. OPs provide early warning and intelligence on enemy activity.
An OP is a covert, economy-of-force element — a small number of observers providing disproportionate intelligence value. Its effectiveness depends on siting, concealment, and communication discipline. An OP that is compromised provides no value and may become a liability.
OP Siting Principles
- Observation: Unobstructed line of sight to the assigned Named Area of Interest (NAI) or sector
- Concealment: The position must not be visible to enemy ground or aerial observation
- Communication: Within range of the parent unit's radio net (or relay plan established)
- Covered routes: Approach and departure routes must not expose the OP team
OP Operations
OP teams operate on a strict reporting schedule. Reports are formatted as SALUTE or PIR-specific intelligence reports and transmitted on a scheduled or event-driven basis. The OP commander initiates reports on CCIR triggers immediately, regardless of schedule.
Duration and Relief
Extended OP operations require a relief-in-place plan. Relief teams use covered routes, staggered timing, and strict noise/light discipline to avoid compromising the position during transition.
