the output of the command is something like:

["Semi (close)","HE Mortar Shells",0]

While first 2 params are obvious, the third one is a mystery. Logic suggests it could be visual mode. Visual mode exists in other commands as well and usually

0 - normal
1 - NV
2 - Thermal

MK6 supports only normal and NV, but the third param in getArtilleryComputerSettings is always 0 no matter what. Could this be a bug?
