While serving in the US Army, Lang graduated from the U.S. Army War College , the U.S. Army Command and General Staff College and the Armed Forces Staff College . He is a decorated veteran of several of the United States' overseas conflicts. During the Vietnam War , he served in the Special Forces and Military Intelligence. 
He was trained and educated as a specialist in the Middle East and served in that region for many years. He was the first professor of Arabic at the United States Military Academy , where he was twice selected as best classroom teacher of the year.
At the Defense Intelligence Agency , he was the Defense Intelligence Officer (DIO) for the Middle East, South Asia and counter-terrorism, and later, the first Director of the Defense Humint Service .  At the DIA, he was a member of the Defense Senior Executive Service . He participated in the drafting of National Intelligence Estimates .

After leaving government service, he joined Veteran Intelligence Professionals for Sanity , but left that group over policy differences. For a period prior to and during the Iraq War , he registered under the U.S. Department of Justice 's Foreign Agents Registration Act , for his work on behalf of a Lebanese politician and industrialist. He promoted the peace process, vocational training for the building trades, English and French-language instruction, and extending microcredit . He registered on advice of counsel and has since deregistered.
Continuing his work on the peace process, he participated in work of the Harry Frank Guggenheim Foundation . As an example: . The foundation sponsors individuals for "scholarly research on violence, aggression, and dominance." In 2006, Lang was appointed to the foundation's board of directors. Lang edits a personal blog on the subjects of intelligence gathering and analysis, military affairs, and war and peace.
Since his retirement from the US Army, Lang has published many articles on intelligence, special operations and the Islamic World.
- , Middle East Policy Journal , August 2004. In 2004, he wrote that members of the Bush Administration manipulated intelligence analysis to strengthen the case for the invasion of Iraq in 2003.
Lang has written and discussed the Israel-Hezbollah July 2006 War , in which he described the Hezbollah defense as a defensive belt which he called the "Tabouleh Line". In an interview with Helena Cobban, he said:
- "A basic lesson of history is that one must win on the battlefield to dictate the peace. A proof of winning on the battlefield has always been possession of that battlefield when the shooting stops. Those who remain on the field are just about always believed to have been victorious. Those who leave the field are believed to be the defeated." 
Iraq and the Middle East
In 2006, Lang said that he thought an American attack on Iran would have deadly repercussions on U.S. occupation troops in Iraq. He noted that "troops all over central and northern Iraq are supplied with fuel, food, and ammunition by truck convoy from a supply base hundreds of miles away in Kuwait. All but a small amount of our soldiers' supplies come into the country over roads that pass through the Shiite-dominated south of Iraq." Iraqi Shiia could easily interdict these supplies, not easily replaced by air, once hostilities start. 
Conflict with Iran
In an interview 2007 he stated that "the U.S. has no plans to bomb Iran" to mean that intensive planning is at an advanced stage but no final decision has been made to push the button. He said the forces are largely in place. The bombing could be carried out by naval air from the aircraft carriers in place, missiles from the screening ships of the carrier groups, and Air Force assets. He says there is dissent in the U.S. administration at high levels whether to bomb Iran, and it is possible for high level resignations to occur even in the uniformed services. He says the concentration of forces has a dual purpose, to prod Iran toward serious negotiations and to be there as a resort if negotiations fail. 
In 2005 he started his blog: Sic Semper Tyrannis (A Committee of Correspondence).  Where he raises points for consideration and invites people to question or add to them. The main focus of the blog are current affairs and politics, with special emphasis on foreign policy, the military, intelligence and the ME. More recently he published two articles of his memoirs in military intelligence.  
Based on his experience in the military and military intelligence and a lifelong interest in the American Civil War, Patrick Lang wrote three novels set in the American Civil War. The trilogy is called: "Strike The Tent: A Tale Of The Confederate Secret Services". His main character is Confederate agent Claude Devereux around whom the historical events unfold.
First volume, "The Butchers Cleaver", published in 2007. In this book Claude Devereux, who like his whole family in Alexandria does neither support slavery nor secession, is forced by events into his role as Confederate agent.
Second Volume, "Death Piled Hard", published in 2009. Devereux's brother Patrick is killed at Gettysburg. But there is not much time to mourn for Claude Devereux, who is slowly finding his way into command circles behind enemy lines.
Third Volume, "Down the Skies", published in 2012. Confederate spy Devereux, by now Brigadier General of the Volunteer Union Forces, not only gained the confidence of president Lincoln but is also getting deeper and deeper insights into the whole administration. But he is suspected of disloyalty, and the Union's Counter-intelligence is on high alert.
