In some important ways, a strongpoint resembles the fire trap. It will be physically located where defensibility and favorable fields of fire will enable the defenders' ability to destroy enemy forces. Attack pilots need to be aware of the character and appearance of strongpoints so that they may also use their lethal weapons against an enemy tied up trying to penetrate or bypass the fortification. Aerial defense of these strongpoints may take on an even more complicated tone and become more crucial if these positions become isolated when a swift enemy advance simply passes by and encircles them. Mine fields placed at any chokepoint, water obstacle, or fire trap will geometrically enhance the target-killing capability of both the ground forces and the attack aircraft.
Timing is critical for optimum results.
If the attack aircraft are on station or on a quick-response ground alert, the ground forces can estimate the time the enemy forces will first reach the mine field and the attack aircraft can then plan to arrive on target at that time. The Soviets, however, are well aware of our predilection for mine field emplacement to create or enhance killing zones. They are prepared to breach the mine fields by placing their lead elements on the forward edge of their own artillery preparation. They envision the first shock troops right behind the bursts of trailing shells. 14 Target discrimination for the attack pilot will be extremely difficult under these conditions.
