Field Artillery is one of the combat arms. Along with Armour, Infantry and Field Engineer units, the Artillery forms the Combat Arms team that fights the enemy. The Artillery contribution to this team is the firepower of the 105mm howitzer, which assists the other arms in their task of closing with and destroying the enemy.
