Before the flag could be raised, before the invasion could be staged, there was the Iwo Jima recon. On February 17, 1945, two days before the invasion, four U.S. Underwater Demolition Teams of about 100 mean each plus 22 Marine observers, scouted the waters around Iwo Jima and went ashore to determine if the soil would support vehicles. Using eyewitness accounts, after-action reports and more than 100 photographs, Iwo Jima Recon brings to life this little-known story of courage above and beyond the call of duty.
