precision is the key to avoiding death and injuries of civilian.
To be precise, location is important. If Astros is not undetected
then there is nothing the airforce, the artillery, LSV, commando or
anybody can do.
If Astros is our prime target in any hostility, then locating the
Astros is one of the primary missions, by all means, at all
cost.
HIMARS is just an additional mean to take out the targets once
located, especially, when HIMARS out range the Astros (depending on
what munitions is used).
Just imagine, when target location identified, it takes time for
F-16 to take off, for apache to approach target, but we only need
to press the button, if target is within range, HIMARS launched,
...good luck to them.
