I am new to CMBO, I am playing a few PBEM games and am having a ball, but I do not know what is what. For example I have a squad called the “Motorized Sqd” I can see there stats and so forth, but what does the Motorized mean, they are on foot, are they supposed to be in a vehicle? A quick segway, can units fire from a vehicle that they are being transported in? So my question, is there a web site that has a breakdown of all units and their meanings that I can use as a resource? Thanks in Advance. Hans
