To use it as other than a terror weapon, the operator would have to obtain the right type of 155mm howitzer, corresponding firing tables, propellant charges and fuses.
Every projectile type has its own unique ballistic characteristics and they are dependent upon the explosive force of the propellant charge, the rifling of the artillery tube, the length of the tube and other factors. While a terrorist could certainly aim the howitzer in the general direction of his target, he would be unable to hit his target without miraculous luck or lot's of practice.

Or they could mount one on an industrial blender and have it come on and spin the warhead. A little trial and error would get them the correct fuse setting. Hopefully they'll get it wrong a few times and leave a trail to the stockpile.
