Iraq actually paid for the 100 Soviet-made T54/55 tanks received from Egypt. Yemen sent a number of brigades that were insufficiently trained and while Iraq schooled them, they were not send to the front for fear that the Yemenis might be taken prisoners. Sudan also sent a brigade, but the Africans were still undergoing training when a domestic crises erupted back home, prompting the Sudanese government to recall the brigade. Jordan sent volunteers, which the Iraqis formed a brigade with and deployed it in their rear areas. The Gulf states gave money, and allowed weapons shipments to pass through their territories. - Adam Geibel
Despite all of the talk across the Arab world in support of Iraq, when the rubber meets the road the Arabs don't supply Baghdad with meaningful assets.
