Persia invades Pakistan. ID-1 tanks push into Pakistani mountains with APCs full of infantry shortly behind. Overhead, swathes of MiG-29s, followed by newer aircraft such as the F-18, fly into enemy air. They intend to establish air superiority and destroy any anti-tank or anti-air emplacements that would threaten control of the first few regions under attack - Quetta, and Peshawar.
Meanwhile, at sea, the Persian navy bombards Karachi and baits the Pakistani navy to defend it. Marines are deployed to siege the city. Mi-8s fly in after marines secure anti-air emplacements, and drop reinforcements.
