Black Storm by David Poyer
It is the eve of America's invasion of Iraq, and Saddam Hussein has threatened to attack Tel Aviv if a single tank enters his country. Though the United States has no intelligence on the type of location of the weapon, Naval Lieutenant-Commander Dan Lenson and a recon team of Marines and military professionals are ordered to eliminate the threat. After a crippling trek into the Iraqi desert, the team successfully locates the weapon in the underground tunnels of Baghdad, only to find that destroying it would unleash a horror more terrifying than anyone could have imagined.
