Title: Control Measures

Action: A graphic of a geographical area with terrain shows visually the rear, close and deep operations with additional information on the FLOT (forward line of own troops).

Voice: The forward line of own troops, or FLOT, is easily understood—it’s the line drawn between us and them.

Action: Graphic shows additional information on the FEBA (forward edge of the battle area).

Voice: The forward edge of the battle area or FEBA is the front line of the battle. Scouts and other screening forces usually decline engagements so the FLOT is usually ahead of the FEBA.

Action: Graphic shows additional information on the FSCL (fire support control line).

Voice: Another very important line is the fire support coordination line or FSCL. It’s a fire support coordinating measure, established and adjusted by land or amphibious force commanders within their AOs in consultation with superior, subordinate, supporting, and affected commanders.

Action: Graphic shows “LCC Controls Fires” behind of the FSCL line.

Voice: Short of the FSCL, all fires of air, land, and sea-based weapons systems are controlled by the appropriate land or amphibious force commander. The purpose of the FSCL is to facilitate the expeditious attack of surface targets of opportunity beyond it.

Action: Graphic shows “LCC Coordinates Fires” in front of the FSCL line.

Voice: Forces attacking targets beyond the FSCL must inform all affected commanders in sufficient time to allow necessary reaction to avoid fratricide. The prevention of fratricide is a primary purpose of all of those lines the Army uses. Ground commanders have been known to halt operations when subordinate units didn’t stay inside of their lines. A crossing-of-lines is one of the most perilous maneuvers a ground force undertakes and is never done without considerable planning. It’s not surprising then that ground commanders demand air operations abide by certain lines. While the placement of the FSCL is often a contentious issue, it is a deadly serious one.

Action: The following text is shown above the graphic:

The land component commander (LCC) is a supported commander in his AO, including its airspace

Voice: It cannot be overemphasized that within his AO, a land component commander is a supported commander. He is responsible for supporting the joint force commander’s objectives within the AO and has considerable latitude for deciding exactly how to do that.
