During President Elpidio Quirino's administration, the Philippine Marine Corps became a prominent political and military institution. The Philippine Marines were established on AFP General Orders no. 319 effective on November 2, 1950. It authorized the creation of Alpha Company of the 1st marine battalion as a unit of the Philippine Naval Patrol (later known as Philippine Navy) whose aim is to create a light and hard-hitting seaborne force that strikes lawless elements along the vast coastline of the archipelago.

Due to the probable hazards of its operation, only volunteers were selected to this special unit. Then LT Senior Grade Manuel Gomez, a graduate of Philippine Military Academy Class ‘41 and a graduate of Armor Tactics in Fort Knox Kentucky was appointed as the first commanding officer. He laid the direct task of training, equipping and organizing the newly established unit.

Meanwhile, LT Junior Grade Gregorio Lim was designated as the executive officer. He became the 'Father of the Philippine Marines" as he organized the first marine company, composed of six navy officers and 230 enlisted personnel, largely World War II veterans, who were trained to conduct amphibious and ground combat operations. Eventually, this later became the cutting edge of the Armed Forces of the Philippines.

Even so, Alpha Company was officially activated on November 7, 1950, at the Naval Operating Base in Cavite due to orders from then-Secretary of National Defense Ramon Magsaysay.

After only five months of training, the unit's first amphibious attack occurred on April 19, 1951 in Umiray, Quezon. But to their dismay, they took their first beachhead without any opposition.

On June 4, 1951, these brave soldiers were put through a baptism of fire in Nueva Ecija. After their daring act in Nueva Ecija, the Marines have never left the combat zone. Nonetheless, they were deployed in almost all parts of the country. While fighting the Huks in Luzon, they also formed detachments of platoon and squad-sized units to fight pirates, smugglers, and other lawless elements along the sea borders of Mindanao.

On July 1, 1951, the Philippine Marines began military operations dubbed as Marblehead, against the Hukbong Mapagpalaya ng Bayan (HMB) in Laguna.

On July 4, 1951, the Marine Company was formally presented to the nation when it marched with other AFP units during the Independence Day Celebration. The following day, the Company was airlifted to Legaspi, Albay and from there the unit launched an amphibious raid against dissidents at Catanduanes.

On September 14, 1951, the Philippine Marines launched Operation Smile in Laguna, where the general headquarters of the HMB was located. After figuring in other military operations, they captured the Visayas commanding officer, Guillermo Capadocia.

The Alpha Company lands on Tawi-Tawi Island to establish a detachment to protect the island from piracy and other threats during the height of the Sulu Sea Frontier Campaign. The Marines took down the banditry and smuggling activities in Sulu. Thus, 'Operation Durian" was launched to capture a known pirate named Hadji Kamlon and his followers in Jolo.

On April 26, 1951, the Marines launched operation 'Four Roses" aimed at capturing the four top Huk Leaders - Taruk, Lava, Sanlo and Dimasalang whose operation areas covered provinces of Central Luzon bordering the Sierra Madre Mountains, Quezon, Nueva Ecija and Bulacan.

On August 1, 1951, Lt Cdr Gregorio Lim took over the command of the company from LCDR Manuel Gomez for the second time.

The Marines were tasked by then-President Ramon Magsaysay to help farmers in Cotabato with rat infestation in March 1954. The Marines sent a platoon headed by Lieutenant Caesar Alzona to the area and accomplished the task well. The Marines undertook civil action projects which endeared them more to the community.

While in Cotabato, the Marines undertook Civic Action Projects, such as construction of an additional school classroom, which endeared them more in the community.

On October 3, 1955, the Marine troops discovered and captured Datu Tagaran, another leader terrorizing Sulu.

On May 23, 2017, the Marawi Siege emerged and was headed by the Maute group with the alliance from ASG emir Isnilon Hapilon during the presidency of Rodrigo Duterte. After unsuccessful operations to capture Hapilon and the counterattacks of the Maute-ISIS Group in the city, the Marines sent one marine brigade with three marine battalions led by Brigadier General Melquiades Ordiales and deployed the Marine Special Operations Group to end the siege.

• The Marines were tasked to recover the Mapandi Bridge (which spans the Agus River and leads to Marawi City) from the Maute-ISIS group. On June 4, 2017, MBLT-7 was able to cross the bridge but was forced to pull back due to fierce enemy fire.
• On June 5, 2017, Marines led by 1st Lieutenant John Savellano recovered cash and checks worth millions, 29 hostages, 29 high-powered firearms, and various ammunition and explosives in a three-story concrete house used as a sniper-and-machine-gun nest by the enemies.

On August 31, the PMC Board of Advisers was created at the height of the ongoing Marawi battle. According to a letter sent by Major General Emmanuel Salamat, he recognized the wisdom of having advisers outside the institution to assist the Corps in achieving their amphibious missions.

• By the third week of September, the Maute-ISIS Group continued with firearms encounters with the Marines, resulting in heavy casualties mostly from the MBLT-7.
• On September 24, the Marines secured Masiu Bridge along with enemy strongholds along Gomisa Avenue and Abubakar As-Sedique Street.

The following day, then-president Duterte declared that Marawi City was finally liberated. The Marine forces' decision to retake the 3 bridges leading into Marawi City enabled fellow forces to re-enter the city and defeat the enemy.

On March 6, Senator Sonny Angara authored SB no. 1731 entitled 'The Philippine Marine Corps Act", it supported the transformation of the PMC as an independent service branch of the AFP. Angara also highlights the crucial role of PMC during the Marawi Siege and deserves to be the fourth branch of the AFP.

The 4th Marine Brigade (provisional) reactivated on January 2, 2019, replacing the Philippine Marine Force-Sulu which served as the command and control of the marine battalion in Sulu.

On March 7, 2019, the Philippine Marine Corps Foundation Inc. was formally launched as part of the PMC Board of Advisers projects. Its president is Lieutenant General Rustico Guerrero, AFP.

Instead of separating the PMC from the Philippine Navy, the Marines were given direct control of their finances by becoming a Key Budgetary Unit (KBU) status directly under the Department of Budget and Management effective in 2020.

• The Philippine Marine Corps published the PMC Roadmap 2020, 2nd Edition. It is a stand-alone document that summarizes the PMC Roadmap 2024 written last 2006. It was necessary to realign the PMC's thrusts with the Philippine Navy Strategic Sail Plan 2020.
• The Philippine Marine Corps is currently writing and reviewing its PMC Roadmap 2028, aligning it with the Transformational Roadmap 2028.

To this day, The Philippine Marine Corps has journeyed through more than seven decades of duty to the country. The Corps has always believed that there is wisdom in winning the peace rather than going to war to defeat the enemy. It has been very effective in the conduct of Civil-Military Operations since then and communities have shown appreciation from the Corps' sincere efforts.

The PMC continues to embody their motto: Karangalan, Katungkulan and Kabayanihan (Honor, Duty and Valor) in every service they render. Finally, with the goal set in stone, the Philippine Marine Corps is ready to become the AFP's Premiere Force in Readiness and the Nation's Force of Choice.

Philippine Marines Corps continues to do historical moments for the Philippines.
