From Aspyr Media:
In Ghost Recon, Russia has fallen to ultra-nationalistic leaders driven to rebuild the Iron Curtain. In Desert Siege, 60-year conflict boils over as Ethiopia invades its smaller neighbor Eritrea, threatening the world's most vital shipping lanes in the Red Sea. Command this elite team of U.S. Army Green Berets through a series of demolitions, search and rescue missions and all-out fights for survival. Select, train and lead the offensive spearhead as the first team deployed and the last team to leave. Ghost Recon and the Desert Siege expansion pack put you in the deadly, realistic combat of tomorrow's battlefields like no other game. If you meet them in combat, you're already dead.
