I've got basically no knowledge of the conflict the game surrounds, but it seems there were lots of artillery pieces present.
Napoleon would've loved it.
From the article:
When it came to purchasing a heavy artillery piece, the Israelis turned to their main armaments supplier, France, buying their Modèle 50 155mm howitzer.
The Modèle 50 was further supplemented the lightweight, but hard-hitting British-made OQF 25 pdr field gun. As well as the original British Quad tractors, the Israeli artillery used the American Dodge ¾-ton and GMC 2½ ton trucks as gun tractors.
