Not a wargames expert, but you could argue the threat of the machine gun kept people in trenches, which of course shaped the war and made artillery a cornerstone. Kind of like how the queen in chess may not take many pieces. She is easily the most powerful piece, and as a result a very credible threat. As a result she can be used to project threats rather than taking pieces.
