Difference between OEF and OIF

Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) are both military operations that were launched in response to the terrorist attacks on September 11, 2001. OEF was conducted in Afghanistan, while OIF was conducted in Iraq. While they share a common goal of combating terrorism, there are some key differences between the two operations. This blog post will explore those differences.

What is OEF?

OEF is a United States military operation that was launched in 2001 as a response to the September 11th attacks. The operation began with the deployment of American troops to Afghanistan, with the goal of unseating the Taliban government and dismantling al-Qaeda’s terrorist network. In the years that followed, OEF expanded to include operations in Pakistan, Iraq, and other countries impacted by terrorism.

To date, OEF is the longest-running military operation in American history. While it has achieved some notable successes, such as the capture of Osama bin Laden, OEF has also been criticized for its high cost and lack of clear objectives. Nonetheless, it remains an ongoing effort to protect America and its allies from terrorist threats.

What is OIF?

Operation Iraqi Freedom (OIF) was the military operation conducted by a multinational coalition to remove the government of Saddam Hussein from power in Iraq, and was codenamed by the United States as “Operation Enduring Freedom” – Afghanistan (OEF-A).

  • OIF is the second phase of the Global War on Terrorism which began after the September 11th attacks on the United States. Saddam Hussein’s government was accused of harboring and supporting terrorist organizations, and having weapons of mass destruction in violation of UN resolutions.
  • OIF began on March 19th, 2003 with the invasion of Iraq by troops from the coalition nations. The capital city of Baghdad was captured on April 9th, and Saddam Hussein’s government fell two days later.
  • OIF resulted in regime change in Iraq, and the installation of a new government led by Prime Minister Nouri al-Maliki. OIF ended on December 18th, 2011, although a residual force remained in the country until December 31st, 2011. As of January 2012, over 4500 coalition soldiers had been killed in OIF, including over 3100 Americans.

Difference between OEF and OIF

  • OEF and OIF are two different terms used to describe military operations. OEF stands for Operation Enduring Freedom, while OIF stands for Operation Iraqi Freedom.
  • OEF is the name given to the U.S. military operation in Afghanistan, which began in 2001. OIF is the name given to the U.S. military operation in Iraq, which began in 2003.
  • OEF was launched in response to the September 11th attacks, while OIF was launched in response to the Saddam Hussein regime’s refusal to comply with UN resolutions. OEF is ongoing, while OIF officially ended in 2010. However, both operations have been criticized for their high cost, civilian casualties, and lack of progress in achieving their stated objectives.


The difference between OEF and OIF military operations is an important distinction to understand. By knowing the difference, we can be better equipped to support our troops who are fighting in these conflicts.
