James T.: Yeah, that's what I was getting at. I was unaware that the UNSC already had artillery.
Anyway, I forgot to mention this. If you are proposing solutions, then ignore that post. I apologize for any inconveniences. \
So Cobalt, do you like it now?
Why WOULDN"T the UNSC have artillery? They're a full fledged army!
OK, admittedly, smaller one story walls would have a place in Halo Wars. Modern military bases have them for a reason: To protect from snipers and spying civilians.
However, the large, three story, garrison troops on top, Helms Deep walls do not fit. The resources and time invested would be ENORMOUS, too large for a short-term base that's going to be glassed anyways.
In any case, such walls were made obsolete with the advent of artillery and aircraft, AA notwithstanding. Do you realize just how inefficient AA is at shooting down bombers and strike craft?
