Hyperveocity can also be achieved through the use of rocket propellant...and we have them, along with the kinetic penetrator warhead at the sword end.

Now you're back to minimum-range issues. It takes much more to accelerate a rocket projectile to V_max. In essence, you're trading minimum range against recoil forces.

Depending on the location of the tank, and whether it was sitting or moving...you can certinly obtain 100m LOS. ie. park one at an intersection.

LOS, of and by itself, isn't difficult.

LOS from a position of concealment (which is kind of necessary to survive firing): rather more difficult.

Our enemy doesn't care about survival after firing.

One tanker dead? Good enough.

They'ed would have preferred to get a news camera in place ahead of time to catch the firing on tape though.

HV through rocket propellant is completely dependant on the propellant and its efficiency...we have some very efficient propellant...can't say what the Ruskies or others may have come up with. Having said that, I have already conceded that the likelihood of these Jihadists having it is very low.

As to your last point, when you are deling with these Islamofascict Jihadists...that point is not as relevant. Their concern about surviving the engagement is not a given at all, therefore they only need to get the shot off.
