It’s in the exact same spot as a previous strike. It’s called a “double tap” attack, and it’s a war crime.
The guy only survived because the bomb went off inside the crater from a previous strike, he would’ve been turned into powder if that had exploded in the surface.
To a degree it is, but target selection is done by human hand. If there is a group of people inside the lethality radius of your bomb, then you are designating them as targets.
Not sure I understood exactly what you’re asking?
I think it was a paveway according to other comments here. Big and heavy, not accurate to the meter, not modern.
Targeting is less important than the weapons technology. Incredibly advanced targeting algorithms still won’t steer a big dumb jobbie from the 1970s any faster under changing wind conditions, for example.
