Mortars

Mortars are becoming a pain with unrelenting fire. But as most people know it is so unrealistic and impossible to fire a mortar continuously. Every other weapon in the game that has unlimited ammo eg mg on a tank, has a cooldown so why not do the same thing with the mortar. Fire 6 mortar rounds then have a cool down then you can fire another 6. The cooldown period can be a way of mortar teams working together to alternate firing to cover the cooldown.
