Terrorists in Iraq are using household items to make roadside bombs and kill U.S. troops. In an effort to prevent further deaths, troops in training are learning unconventional battle techniques.

A new wave of soldiers will deploy to Iraq starting in February to replace troops who are completing their tours of duty. National Guard soldiers training at Camp Atterbury (search) in Indiana will soon head to Iraq and are learning that the battlefield is no longer conventional — troops are up against ambushes and improvised explosive devices — IED's for short.

"Coke cans, batteries —- The Energizer Bunny is a good friend of the enemy for IEDs," said Maj. Leslie Chapman, a training instructor. "Anything that can cause a fire ... cause an explosion."

The mission in Iraq will rely heavily on these new reserves, who make up about half of the 100,000-strong force making up the next wave of troops to serve in Iraq.

Lt. Charles Wilkins said he's ready for the challenge, along with the rest of his 216th Engineering Battalion.

"It's not like a conventional enemy," Wilkins said. "He's over there. I'm over here. This is a little different. You've got to stay on your toes. You've got to be ready."
