Unit-336: KC-360 STRIX should use the same icon as unit-335 KC-360 AMV AMOS. These are the same vehicles the other one just has the armor piercing strix round's for its 120mm twin tube AMOS mortar system. The icon currently allocated for KC-360 STRIX looks like the Patria IFV vehicle icon that has the 30mm autocannon.
