Charts, Photo, & Objective Cards
The following tips are used for preparing charts, photographs, and objective cards:
- Post charts, photographs, and objective cards (not kneeboard) in the sequence of discussion during the OPORD brief. Accurately construct charts and objective cards. Label charts and objective cards not reproduced to scale as “not to scale.” Place required items on charts, and refer to them, as necessary, during the mission brief.
- Prepare and orient charts and objective cards in the direction of approach, relating to magnetic north or in the direction of landing/takeoff. Photos and overhead imagery should be oriented as if viewed from the direction from which they were obtained.
Include the following information on the objective card diagram:
- Name of objective area.
- Grid: military grid reference system or latitude/longitude.
- Landing direction.
- Landing formation.
- Frequency and call sign.
- Passenger entry/exit.
- Go around direction.
- Weapons control status/measures.
- Fields of fire.
- Hazards and markings.
- Key terrain.
- Alternate (if required).
