Organized forces in time of war or any hostile body, including civilians, that may oppose U.S. forces. United States v. Monday , 36 C.M.R. 711 (A.B.R. 1966), pet. denied , 37 C.M.R. 471 (C.M.A. 1969).
A question of tactical relation not of distance. A reasonable possibility of being called into action is sufficient. United States v. Sperland , 5 C.M.R. 89 (C.M.A. 1952).
Subsequent enemy contact may not be used to establish misconduct before the enemy. United States v. Terry , 36 C.M.R. 756 (N.B.R. 1965), aff’d , 36 C.M.R. 348 (C.M.A. 1966).
Shamefully abandoning, surrendering, or delivering up command, unit, place, ship or military property.
Casting away arms or ammunition.
Quitting place of duty to plunder or pillage.
Willfully failing to do utmost to encounter the enemy.

That this conduct was the result of fear.
Cowardice is misbehavior motivated by fear. Fear is the natural feeling of apprehension when going into battle. United States v. Smith , 7 C.M.R. 73 (C.M.A. 1953).
The mere display of apprehension does not constitute the offense. United States v.Barnett , 3 C.M.R. 248 (A.B.R. 1951).
An intent to avoid combat does not in itself justify an inference of fear. United Statesv. Yarborough , 5 C.M.R. 106 (C.M.A. 1952).
Refusal to proceed against the enemy because of illness is not cowardice unless motivated by fear. United States v. Presley , 40 C.M.R. 186 (C.M.A. 1969).
Article 99 covers the area of misbehavior before the enemy offenses. Art. 134 is not a catch-all. United States v. Hamilton , 15 C.M.R. 383 (C.M.A. 1954).
