"Will some soldiers hear this, read this and say 'Well that's nothing?' Sure, they might," Cuculo said. "But I've got 22,000 incredible soldiers who are incredible Americans and I'm counting on them to do the right thing." Of the soldiers in his command, 1,682 are women.
Cucolo said the Army does not provide emergency contraception or abortive services and does not intend to start.
There's "only discussion about appropriate behavior and consideration of the impact of getting pregnant, of getting someone pregnant," he said. "That's the only discussion that's taken place. Nothing about pills."
"Anyone who leaves this fight early because they made a personal choice that changed their medical status -- or contributes to doing that to another -- is not in keeping with a key element of our ethos, 'I will always place the mission first,' or three of our seven core values: loyalty, duty and selfless service," he continued. "And I believe there should be negative consequences for making that personal choice. "
The pregnancy policy was just one provision in a larger general order that also prohibits soldiers from sexual contact with Iraqis or third-party nationals who are not members of coalition forces.
U.S. military leaders in Iraq conducted a full review of all existing orders as part of the ongoing transition in Iraq, and a new general order has been drafted. The order would consolidate several general orders from the U.S. commanders across Iraq.
Previously, the commanders have had the authority to draft their own restrictions.
