For the next nine months, 3rd Battalion would conduct advanced training out of Camp Coconut Grove near the Tetere Beach. No fewer than three major amphibious assaults would be planned from here. The
invasion of Bougainville, announced on 27 September, was the first.
Bougainville (1943)

On 1 November 1943, the 3rd Battalion landed at
Cape Torokina with the rest of 3rd Marines, just east of the Koromokina River. While resistance was extremely light, the rough surf and dense jungle (which in many places extended all the way to the water) resulted in numerous landing craft being lost or damaged beyond repair.
For the next two weeks, the battalion helped construct a series of trails that linked the beachhead with the advancing units, and made supply much easier. On 16 November the battalion reached the Numa Numa Trail and began probing for Japanese units. On 18 November after a sharp firefight near a Japanese roadblock the battalion recovered a Japanese map with valuable intelligence on Japanese defenses. From 19 to 21 November, 3rd Battalion continued probing for Japanese units, which had been identified as elements of the 23rd Infantry Regiment, and engaging in sporadic firefights. In the lead-up to the
Battle of Piva Forks, 3rd Battalion seized critical high terrain that would give the Marines the advantage in the upcoming fight. The actual battle, from 22 to 26 November, saw some of the most vicious close combat experienced in the Pacific War as of that date. 3rd Battalion additionally suffered many casualties from unusually accurate Japanese mortar and artillery fire. Two days later, after 27 days of continuous action, 3rd Battalion was moved to a relatively quiet sector on the 3rd Division's flank where it remained for the remainder of the operation.
In December, the 3rd Marine Division was relieved by the
Army's Americal Division and 3rd Battalion left Bougainville for Guadalcanal on Christmas Day, 1943 with the rest of the division. They left behind 36 of their comrades, including Corporal John Logan Jr. and Captain Robert Turnbull (Lima Company), who were both awarded Navy Crosses during the
Battle of Piva Forks. 165 other Marines from 3rd Battalion became casualties during the campaign.
After Bougainville, 3rd Battalion conducted numerous training exercises on Guadalcanal from January to May 1944 in preparation for the invasion of

Within minutes, the Japanese defenders opened up with mortars and machine guns, hitting many 3rd Battalion Marines coming ashore. By 0912, battalion commander Lieutenant Colonel Ralph Houser reported many casualties caused by both mortars and sniper fire. Both Kilo and India Companies rushed the Chonito Cliffs but the Japanese defenders (Elements of the 2nd Battalion, 18th Regiment and 320th Independent Infantry Battalion) resisted strongly, in some cases rolling grenades down the hillside.

[''Central Pacific Drive'' pp. 463–456.] After securing Adelup Point, 3rd Battalion finished the day providing flank security for the rest of the 3rd Marines during the Battle for Bundschu Ridge and became the only unit in the regiment to accomplish its objectives by the end of W-Day.
The first night of 21–22 July, the Marines of 3rd Battalion came under a concerted counterattack by the survivors of the Japanese 320th Independent Infantry Battalion, as well as the 319th, committed by Japanese commander General Kiyoshi Shigematsu to retake the Chonito Cliffs. The Japanese managed to infiltrate past many 3rd Battalion units through ravines and dry river beds and briefly threatened to overrun the battalion command post. The fighting was so heavy that parts of the Division Reserve were committed. Additionally, the destroyer ''
USS McKee'' was unable to provide close fire support, as the Japanese and Marines were so closely intermingled.
[''Central Pacific Drive'' pp. 484–485.] However, the Marines managed to repulse the attack by 0830.

Over the next two days, the 3rd Battalion battled with the Japanese defenders for the Chonito Cliffs and Fonte Plateau area, as the battalion struggled to capture the Mt. Tenjo Road. On 23 July, 3rd Battalion seized the last ridge leading to the Fonte Plateau, provoking a heavy Japanese counterattack. LtCol Houser was seriously wounded in this engagement, resulting in the

, Maj. Royal Bastian, to take command.
The 3rd Battalion, then reinforced with tanks, took part in the assault on the Fonte Plateau on 25 July, seizing the key position after an hour of fighting. The night of 25–26 July saw the climax of the fighting on Guam when the Japanese launched a counterattack against the Americans. In the 3rd Battalion's sector, Japanese sailors of the 54th Keibitai launched a series of failed attacks against the now-well defended Marine positions. Backed up with artillery, the Marines easily repulsed the Japanese.

On the morning of 31 July, 3rd Battalion proceeded east on the Mt. Tenjo road towards the island capital of
Agana, which it liberated the same day after token resistance. By 1045, 3rd Battalion had reached the central plaza and stopped at the northern outskirts by noon.

. For the remaining ten days of the campaign, the battalion marched northeast up the coast, encountering occasional Japanese resistance until the island was declared secure on 10 August. However, the Japanese were not totally defeated. On 7 August, as 3rd Battalion led the regimental advance towards Road Junction 460, Japanese artillery shells began landing among the advancing Marines. After Marines discovered the source of fire—a 75mm artillery piece—the Japanese fled. The final action by 3rd Battalion during the campaign was on 9 August when a nearby battalion came under heavy Japanese tank and infantry attack. Blazing a trail through the jungle, 3rd Battalion rushed towards the action but the Japanese tanks vanished before the battalion could arrive. Casualties for the 3rd Battalion were twice that of Bougainville, with 300 wounded and 97 killed.
Iwo Jima and Japan (1945)
Following the invasion of Guam, 3rd Battalion spent two months conducting 'mopping up' operations on the island until November, when it received orders to prepare for operations against Iwo Jima. From November until February 1945, they took part in a rigorous training regimen that reportedly left a minimum of 20% of its members incapacitated due to foot and heat injuries. During the

After sitting off Iwo Jima in their transport ships for a month, the 3rd Marines were ordered to return to Guam on 5 March 1945.

3rd Battalion's commander, LtCol Gary Wilder, believed he was only facing a small PAVN unit and counterattacked.
Throughout the 25th, 3rd Battalion launched a series of piecemeal attacks on the hills, only to be repulsed with heavy losses. The 3rd Marine Division committed its reserve to the fighting and took Hill 861 on 26 April. On the night of 29 April, the PAVN replaced the battered 18th Regiment with the fresh 95th Regiment.
The following day the Marines dropped 250 bombs and more than 1300 artillery rounds on Hill 881.
Mike Company was allowed by the PAVN to advance partially up the hill before opening fire. By the end of the battle, 46 marines from the battalion were killed, half of them from Mike Company.

Pinkerton was first to push a squad to the Dealer 54s crash site through heavy Taliban Machine Gun fire and set up a safe perimeter to keep Taliban fighters from getting to downed pilots.
Around this time, India Company conducted Operation Thresher and later Operation Mako in areas of Nawa District under heavy Taliban influence, finding several cache sites and taking some detainees.
In September, while providing pre-election security for the
Afghan parliamentary elections the battalion suffered another loss when 1st Lieutenant Scott Fleming was shot and killed. Nevertheless, on election day Nawa District was the one location in Helmand Province with no reported Taliban attacks. Residents claimed that the Marines from 3rd Battalion had implemented good security measures and encouraged the people to cooperate with the government, preventing the Taliban from firing a single shot. By the end of 3rd Battalion's deployment in the fall of 2010, Nawa was regarded by many as "a model of counterinsurgency operations and the most stable district" in southern Afghanistan.

In October 2011, 3rd Battalion deployed again to Helmand Province, this time to the
Garmsir District

Starting in January 2012, 3rd Battalion and elements of the 215th Corps of the Afghan National Army began a series of airborne assaults at sparsely-populated and historically Taliban-controlled areas in Garmsir.
On 4 January they launched Operation ''Tageer Shamal'' (Shifting Winds), aimed at clearing Taliban fighters from the western side of the

Haditha killings (where Marines had killed 24 civilians in the same area the previous November) broke in the United States.
Once it arrived in Iraq, the 3rd Battalion began the mission of "fighting insurgents, working with locals to improve local economy and quality of life, and training Iraqi soldiers."
The Battalion was also partnered up with the 2nd Battalion, 2nd Brigade of the
7th Iraqi Army Division.
3rd Battalion attempted to secure Haditha by using an approach of "constant presence". The battalion operated from a series of

Baghdadi from which its rifle and weapons companies sent out constant patrols to keep the insurgent groups off balance.
However, the battalion was unable to create a working local police force, due to the overwhelming intimidation by insurgent groups.
Battalion Commander Lieutenant Colonel
Norman Cooling observed, "We didn't have the manpower to control the
ain roadsand hold Haditha. The Iraqi Army was as blind as we were. The insurgents killed anyone who spoke to us."
[ p. 182] One group of 15 police volunteers was murdered by insurgents in Baghdadi in May.
Then in June a Marine mistook a local tribal leader driving near a convoy for a possible suicide bomber and killed him.
Another groups of Marines in the same city had more success when they cornered a band of insurgents in the Haqlaniyah Hotel and destroyed it.
By June, attacks against Marines in Haqlaniyah had become common, with their base getting mortared about twice a week and some insurgents getting close enough to throw grenades over the wall into the base.
On 3 June three insurgents opened fire on the Haqlaniyah base but were quickly killed after a group of Marines led by
Gunnery Sergeant Jim Lanham launched a hasty counterattack.
In early September, 3rd Battalion launched a second effort to recruit police called Operation Guardian Tiger IV. This recruitment drive was more successful than its predecessors and also detained 30 suspected insurgents.
This second recruitment effort succeeded in locating an individual named "Colonel Farouk," who would play a key role in the counterinsurgency campaign in the region subsequent to 3/3's departure, when the
2nd Battalion of the 3rd Marine Regiment, 3/3's sister battalion, continued counterinsurgency efforts in the area of operations. Farouk would prove critical to these continuing efforts. Al Qaeda in Iraq was ultimately defeated in the region, due in great measure to 3/3's returning Farouk, who built a robust police force during 2/3's tenure, to the Haditha region.
During their time in Haditha the Marines from 3rd Battalion 3rd Marines conducted more than 8,000 patrols, located 54 weapons caches and detained more than 800 suspected insurgents. The battalion suffered 13(11 was wrong, I was there....) marines killed and 85 wounded. On 6 October, 3rd Battalion 3rd Marines returned to Kaneohe Bay.

The following year in August 2007, the battalion made its second Iraq deployment, this time to the

and Fallujah. Unlike other cities, Karmah had no definable perimeter to hold, making it easy for outsiders to access. In addition, as insurgents were pushed out of Baghdad by other offensives they found it easy to flee to Karmah.
In early September, Kilo Company moved into a cluster of villages northeast of Karmah that was the last major insurgent staging ground in Anbar. The insurgents fled without firing a shot. For the first few months the Marines took small-arms and mortar fire nightly. A 20-minute attack on 5 October against the Iraqi Police station in Karmah was repulsed by Jim Lanham, now a

three-block war here and it's very, very dynamic." The battalion spent more than $1 million on Karmah, including a city council and a medical clinic. On 1 December, the battalion staged an elaborate reopening of "Victory Circle", or "The Lollipop", the marketplace in the center of Karmah which had earlier been the scene of fierce fighting between Marines and insurgents.
In February 2008 the battalion rotated back to the United States without suffering a single casualty.
