History

World War II 3rd Battalion 7th Marines was activated 1 January 1941 at Guantanamo Bay, Cuba and was assigned to the 1st Marine Brigade. In February 1941 they were reassigned to the 1st Marine Division.

Due to the situation in the Pacific, the 7th Marines were detached from the 1st Marine Division and sent to American Samoa with the Third Battalion being the first to arrive on 28 April 1942.p. 7 https://www.marines.mil/Portals/59/Publications/A%20Brief%20History%20of%20the%207th%20Marines%20%20PCN%2019000308200_1.pdf Companies I and M landed at Wallis Island on 27 March 1942 along with Free French forces to deny the Island to Vichy France.

3/7 participated in the following World War II campaigns: Guadalcanal. New Britain. Peleliu. Okinawa.

After the war 3/7 participated in Operation Beleaguer in northern China from September 1945 to April 1946 and then deactivated 15 April 1946.

Korean War The battalion was reactivated 11 September 1950 at Kobe, Japan and assigned to the 1st Marine Division. They deployed in September 1950 to the South Korea and participated in the Inchon-Seoul. Following the recapture of Seoul, the 1st Marine Division was pulled out of northwest Korea and sailed to the east coast where they landed at Wonsan in late October and began to march north towards the Yalu River.

The battalion was in Yudam-ni on the evening of 27–28 November 1950 when the Battle of Chosin Reservoir began. On the first evening, the Marines of "How Company" were overwhelmed on Hill 1403 by waves of Chinese attackers and were eventually ordered to pull back by the commanding officer (CO), Lieutenant Colonel William HarrisRuss (1999), pp.115–121 The battalion continued to fight on the hills around Yudam-ni for the next few days until 1 DecemberRuss (1999), p. 305 when the 5th Marines and 7th Marines were ordered to fight their way back to the 1st Marine Division's main perimeter at Hagaru-ri. The 300+ remaining members of 3/7Russ (1999), p. 324 provided the rearguard for the two regiments as they broke out to Hagaru-ri and were the last Marines to leave the perimeter at Yudam-ni as it was being overrun by Chinese forcesRuss (1999), p. 326 3/7 consolidated with the rest of the division at Hagaru-ri and took part in the fighting breakout towards Koto-ri where, on 7 December, all of the 1st Marine Division's regiments were together for the first time since the landing at Wonsan in OctoberRuss (1999), p. 394. Of note during the battle, on the morning before their arrival at the Koto-ri perimeter, the battalion's CO, who during the battle was described as "coming apart"Russ (1999), p. 121 and having an "emotional breakdown and collapse",Russ (1999), p.168 disappeared and was never seen again.Russ (1999), p. 371. After the withdrawal from Chosin the 1st Marine Division was evacuated from Hungnam.

During the rest of the war 3/7 took part in the fighting on the East Central Front and then the Western Front of the Jamestown Line. In October 1951 it performed the first battalion sized combat helicopter air assault in history in Operation Bumblebee. After the war the battalion participated in the defense of the Korean Demilitarized Zone, July 1953 to March 1955.

Vietnam War The 3rd Battalion, along with the rest of the 7th Marines, was deployed to Vietnam from Camp Pendleton in late May 1965. The 3/7, under the command of LTC Charles H. Bodley, embarked on the amphibious ships , , and at Okinawa on 24–26 June and landed near the city of Qui Nhon on 1 July 1965.Victor J. Villinois, A Brief History of the 7th Marines, 1965–1970, http://www.marzone.com/7thMarines/Hst0001.htm, accessed 22 July 2012.

On 18 August 1965, the 3/7 took part in Operation Starlite, the first regimental size operation by US forces since the Korean War. The 3/7, along with the 3rd Battalion, 3rd Marines, and the 2nd Battalion, 4th Marines, made a combined amphibious-helicopter assault on fortified enemy positions on the Van Tuong Peninsula. The Marines landed behind enemy lines and, after seven days of fighting, drove the Viet Cong (VC) 1st Regiment into the sea.Villinois, A Brief History of the 7th Marines.

In January 1966, the 3/7 took part in Operation Mallard along with the 3rd Battalion, 3rd Marines. It was a sweep of the area 20 miles southwest of Da Nang, in the area later known as the Arizona Territory. While the VC did not engage in major confrontations with the Marines during Operation Mallard, the area would later be a significant battleground for the 3/7 and other Marine battalions in the years to come.Villinois, A Brief History of the 7th Marines

In March 1966 the battalion took part in Operation Texas. On 18 March 1966 an Army of the Republic of Vietnam (ARVN) outpost on Hill 141 west of Quang Ngai City was overrun by the People's Army of Vietnam (PAVN) 36th Regiment. A reaction/relief force was promptly put together consisting of elements from 4 Marine battalions including 3/7 and an ARVN battalion. The allied forces were inserted by ground and air on 20 and 21 March and began closing around the PAVN forces. Over the next four days, Operation Texas claimed a total of 623 known PAVN dead, but at least 57 US Marines and sailors were killed in a series of bitter fights.

Along with the 1/7, 2/7 and elements of the 26th Marines and 51st ARVN regiment, the 3/7th also took part in Operation Oklahoma Hills from March through May 1969, an operation to clear PAVN base camps and infiltration routes out of the hills and valleys southwest of Da Nang, South Vietnam's second most important city and a major base for US operations at the time.Charles Richard Smith, U.S. Marines in Vietnam: High Mobility and Standdown, 1969 (Washington, DC: History and Museums Division, Headquarters U. S. Marines, 1988), pp. 103–116.

For "conspicuous gallantry and intrepity at the risk of his life above and beyond the call of duty" and "in the face of vicious enemy fire" during a search and destroy mission in the Que Son-Hiep Duc Valley on 28 August 1969, in which he destroyed several of the enemy and silenced anti-aircraft guns and machinegunist, Lance Corporal Jose F. Jimenez of Kilo Company, 3/7, was posthumously awarded the Medal of Honor.

Persian Gulf War

During the 1990–91 Persian Gulf War, 3/7 took part in Operation Desert Storm. The battalion arrived in Jubail, Saudi Arabia, in mid-January 1991, with the mission to be a foot-mobile infiltration force. For a month from mid-February onwards, 3/7—as part of Task Force Grizzly, which mainly consisted of 3/7 and 2nd Battalion 7th Marines—took up position along a berm near the Saudi–Kuwaiti border. There, 3/7 became the lead element of all U.S. forces in the region. The battalion moved out of Saudi Arabia and into Kuwait three days before the ground offensive began on 24 February, and then became the first allied infantry force to enter Kuwait. After breaching two enemy minefields, 3/7 took over Ahmad al-Jaber Air Base, which was believed to be the main command post for all enemy forces in Kuwait. The battalion departed Saudi Arabia in early March.

Somali Civil War

From January to March 1995, elements of the battalion—namely Kilo Company, augmented with elements from India Company, Lima Company, and Weapons Company—participated in Peacetime Enforcement Operation, Operation United Shield in Somalia. The operation was the closing chapter of United Nations Operation in Somalia II (UNOSOM II). A Combined Task Force (CTF), commanded by the United States, including two ships of the Pakistan Navy, two ships of the Italian Navy and six ships of the United States Navy evacuated all UN Peacekeeping Forces from Somalia.

On 27 February 1995, minutes before midnight, 3/7 executed an amphibious assault on the city of Mogadishu, part of a mechanized force consisting of about 1,800 US Marines and 350 Italian Marines. Aboard LCUs LAVs, AAVs, and LCACs the joint task force secured Mogadishu International Airport and New Port. The entire amphibious landing was complete by 0430 on the morning of 28 February, and evacuation procedures immediately commenced.DefenseLink, U.S. Department of Defense: UNITED SHIELD Press briefing, 28 February 1995

By 3 March 1995, 73 hours after the beginning of the amphibious landing, all 2,422 United Nations troops, approximately 3,800 CTF troops and over a hundred combat vehicles had withdrawn without any loss of life among any of the coalition forces.

Global war on terror (GWOT) Operation Iraqi Freedom 2003 - 1st Tour

3/7 was part of the main effort, and took a major role in the 2003 invasion of Iraq. They originally deployed in January 2003, moved north in March and reached Baghdad by April – securing several cities, military bases, terrorist training facilities, and various other objectives along the way. They then moved south for a five-month security assignment doing stabilizing operations in Karbala until September 2003. During the assignment, India Company, 3rd Battalion 7th Marines operated in Mahmudiyah, Iraq in support of Task Force Scorpion during July and August 2003. India Company's training in the Kuwaiti desert and the subsequent invasion was covered in the TV documentary Virgin Soldiers which often airs on Discovery Times and Military Channel.

2004 - 2nd Tour After returning to the United States in September 2003, the battalion re-deployed in February 2004 to Al Qaim—in western Al Anbar Province, abutting the Syrian border. Their area of responsibility included Husaybah, the primary border-crossing point between Syria and Iraq. Increased military presence resulted in continuous fighting, including large-scale operations to retake the city of Husaybah from insurgents and local fighters in April. The Medal of Honor was posthumously awarded to Kilo Company squad leader Jason Dunham for actions in the city of Karabilah. They returned from that deployment in September 2004.

2005 - 2006 - 3rd Tour

From September 2005 to March 2006 3/7 was stationed in Ar Ramadi and made FOB Hurricane Point (HP) and Camp Ramadi their main base of operations; however most infantry units operated out of firm bases and outposts within the city.

2007 - 4th Tour From May 2007 to November 2007 3/7 was once again stationed in Ar Ramadi and made FOB Hurricane Point (HP) and Camp Ramadi their main base of operations. They dispersed throughout the city to increase contact with the local residents. Since the prevalence of the Anbar Awakening, 3/7 Marines began conducting counter-insurgency (COIN) missions rather than the more "kinetic" operations on previous tours.

2008 - 2009 - 5th Tour 3/7 re-deployed in support of OIF again in August 2008, once again to the Al Qaim area—in western Al Anbar Province, abutting the Syrian border. Due to status of forces agreements with the Iraqi government, operations were very limited and the battalion served in an "operational overwatch" role for the Iraqi forces. They returned from that deployment in March 2009.
