You guys bring up a lot of points. That would explain why the Covenant always loses on the ground (most of the time anyways).

But why don't they use handheld railguns?

And it takes a MAC round to take out the shields of a CCS-ship. Why not use a plasma weapon to take out the shield, then hit the ship with one well-placed MAC round?
