Towed Artillery
From Conflict of Nations Wiki
Artillery is the most lethal form of land-based armament in use today. Designed to fire munitions far beyond the scope of infantry capabilities, towed artillery, such as the M777 Howitzer seen below, can be towed by a land vehicle or transported by either helicopter or plane to any location on the globe. They fire shells in a high trajectory on stationary targets, and are especially effective in preparing assaults on defended positions.
