I think I remember reading a thread a long time ago mentioning that limit artillery attacks to ballistic weapons types, its just that there hasnt been any energy weapons with an artillery attack, and that it would be weird and unlikely for WKs to make one.

That being the Nova Cat Steel Wolves situational alliance can change ballistic attacks to energy and vice versa. So would it then allow for an energy artillery attack?

Would it give a mech an extra click of heat when it hits?

Other than that the only other thing I see it being useful for is getting around reactive armor.

No. The alliance allows you to change damage types at the start of your order phase, but artillery resolves during the command phase.

Also useful for turning a CNC energy 'Mech into an infantry killer, or for bypassing either kind of armor, or for use with, say, Alpha's attacks to allow it to deal heat as well as damage.

I would have to say that you could give it an artillery attack as there is no rule saying it is limited to ballistic type, and that any mechs would take a heat because it doesn't specify that they must be the tarrget, only that they must take damage.

That being said though Infantry would take one click of damage total as it is energy damage.

if anyone can point out anything that says otherwise, please feel free to do so as I don't think this is correct but can't find anything in the rules saying otherwise.

Disregard my post, Cloudmoon found the answer before I did, and it was something I missed.

It woudl be really sweet if it switched SE for that attack. Go from pulse to AP and AP to pulse...

Yeah I knew that, I was referring to the usefulness of energy artillery, not the usefulness of switching damage type.

energy artilary is possible, just lob a shel that explodes and send beams of energy everywhere.
