> The system functions as follows. The observer determines the target location (e.g. map coordinates or bearing and distance from their own position), ensures that their laser target designator can 'mark' the target and requests or orders a fire mission against the target using Krasnopol. A gun is then aimed at the target location and a guided shell is fired. The firing unit uses their 1A35K command device to send a signal via a communications link confirming the firing of the projectile to the 1A35I observation post device with the observer. The laser target designator is then used to illuminate the target and the in-flight projectile detects the radiant laser energy reflected by the target and the navigation system steers the shell towards the point of greatest incident energy—the designated target with top attack pattern. The iris of the optical seeker head is protected by a cap which is ejected by a mechanical timer upon firing.
Low visibility conditions are of course a deterrent against this type of attack.
