The morning-after pill will soon be available at U.S. military bases around the world.
For the first time, the Pentagon has ordered all military facilities to stock the emergency contraception, a military spokesman announced late last week.
The decision follows the recommendation of an independent medical panel, which determined the drug should join the military's required list of medications that must be stocked at each U.S. military facility.
The pill is designed to prevent fertilization, but it can also prevent the implantation of a fertilized egg.
The Bush administration tried to keep the morning-after pill out of the military. However, pro-choice groups fought for women in the armed forces to have the drug.
Wendy Wright of Concerned Women for America told CBN News the pill is "a political tool for abortion advocates" and that "the military needs to focus on discipline and proper behavior, because lives depend on it, not promoting risky behavior."
Defense Department spokeswoman Cynthia Smith said she did not know when the policy would be implemented.
