From the article:
The armies of this Great War rely heavily on artillery to help prepare the enemy for an assault or to break up enemy attacks. The 7.7cm FK96 n.A. is a versatile field gun used all across the front. Its light weight makes it a very mobile gun compared to its competitors.
With a variety of shells available, ranging from anti-tank to shrapnel rounds, this gun can be employed successfully in different combat situations. This gives commanders a valuable tool in both offensive and defensive operations.
