Tényleg nem kötözködésként de az általad linkelt Blog (ami szerintem nagyon jó!!) is az alábbiakat írja a Hunter-Killer képességről:
"Contrary to popular belief, a hunter-killer regime is not at all exclusive to modern Western tanks. Rudimentary hunter-killer cooperation dates back to WW2, where commanders would have to yell out the direction of the target by referring to the angle indicated on his cupola's race ring. The gunner can then slew the turret towards the target by referring to an azimuth indicator corresponding to the commander's, usually marked out on the turret ring.
In 1951, the T-54 obr. 1951 pioneered a semi-automatic system where the commander only has to press a button on his TPK-1 optic to activate the electrical turret traverse drive and slew the turret towards whatever target he is viewing through his optic.
The T-72, like the T-64, T-62 and T-54 before it, has this feature as well. As you would expect, the commander takes on the role of the hunter in the hunter-killer system. At the end of the left hand grip of the TKN-3MK is a button to initiate turret slewing to aim at whatever the commander has his crosshairs on, in the same way as the T-54 system with the TPK-1. Unlike the T-54, though, the T-72 features an additional electric motor that automatically counter-rotates his cupola so that his original orientation is preserved while the turret is spinning. Most Western tanks of the 50's and 60's and beyond already had the same hunter-killer feature, with some notable exceptions like the M1 and M1A1 Abrams, which did not have a similar feature until the M1A2 variant came about."
