AI Tanks no longer use machine guns and refuse to fire on planes

[SCG_Limboski]

I created a mission where tanks attack an airfield and I noticed that tanks refuse to engage aircraft regardless of how they are instructed to attack (i.e., Attack Area MCU set to air and ground targets, waypoint move order, and directed Attack MCU against a plane).  My conclusion is that tanks no longer use their secondary weapons, their machine guns (MGs), anymore.  Previously they used to fire their Mgs but at some point this behavior has stopped.  I think this is bug.
