Does the artyllery computer work with special ammo?

[bluesilence 12]

With the guns' default ammo, me or any AI squad member can fire with pinpoint accuracy. However, if I load special ammo (laser guided, SADARM, smoke...) the arty computer (and pretty much the arty itself) becomes useless.

If I order the AI to fire at a position, it tells me that it cannot fire there.

If I try to use the arty computer myself, my rounds land somewhere else. I can only hear a distant explosion.
