The range for shallow water is18 to 22° and for open sea or deep water is 22 to 32°. Extreme angle to be avoided. A Grumman TBF aircraft in flight. The aircraft releases torpedo in water. Estimation of correct amount of lead depends on speed of target and target angle. Thumb rule explains the aiming allowance for ship vessels. The ship underway at sea takes a turn. (World War II period).

A diagram shows the gliding of torpedo at target area. The aircraft in flight. Torpedo attack to be coordinated by dive bombing, strafing or rocket attack. (World War II period).
New dropping tactics in aerial torpedo attack, in the United States. A ship underway at sea. Attack using the high speed and high altitude combination and using evasive maneuvers. An aircraft in flight. The aircraft releases torpedoes at different angles in water simultaneously to attack the target area. Target ship maneuvers out of way. Torpedoes track in various directions through the water. (World War II period).
Opening scene shows military police, with jeeps and motorcycles, in front of the Lampasas County Courthouse, where they simulate an occupying enemy force.
