Sorry, but what point describes indescriminate killing?
They are on the contrary describing a very rigid procedure to determine the correct target, and then hitting the correct target.
The exact opposite of what you claim.
find – identifying an enemy object using intelligence, surveillance, and reconnaissance (ISR) capabilities;
fix – determining the object’s precise coordinates and confirming its status;
track – continuously monitoring the target’s movement in real time;
target – selecting the most appropriate kinetic or non-kinetic means of engagement to accomplish the mission;
engage – employing a weapon against the target at the designated coordinates;
assess – analyzing the effects of the strike to determine whether re-engagement is necessary.
