When Indian army regiments, with predominantly Sikh soldiers, fight any army, they rally themselves for battle with cries of "Wahe Guru ki Khalsa, Wahe Guru ki Fatah" (which roughly translates to "[We] the pure are of the almighty, and the triumph in making is also of the almighty). Pakistani army, predominantly Muslim soldiers, do use the rallying cry of "Allahu Akbar". It's debatable whether these chants are meant more for themselves, than directed at their "enemies".
