Ambassador is a heavy missile truck with unmatched range within T2 mobile units. It shoots missiles along a high-altitude arc enabling you to take down targets covered by walls and hilltops.

It's awesome range makes it a perfect siege weapon

Able to quickly obliterate enemy’s defensive structures and destroy strategic targets like geothermal powerplants etc. It is very costly but its huge damage output makes it worth a shot. Helpless against mobile units, always keep it protected by your infantry.
