Back2Fronts is an extensive mod that will overhaul your Call of Duty 2 game to a next level. This mod brings more variety, intensity, realism and battle-like experience. Try new weapons, fight new enemies, fulfil new missions and explore new options. Mod is SP and MP friendly (although primary part is SP).
The script coping with artillery in the game has been edited to add a new artillery weapon - the British 6-pounder QF anti-tank gun which you can see in this video along with usage of FlaK88 and PanzerFaust. These weapons give you more ways to kill heavy equipment like tanks.
