Since the start of President Felipe Calderón's war on the drug cartels, the Infantería de Marina's role has grown from maritime and port security to land based operations in combating organized crime, drug trafficking, extermination of marijuana fields, drug interdictions at sea, and also participating in arrest of cartel suspects.[5]

The Navy has carried out permanent intense anti-narcotic operations. Such tasks as the extermination of marijuana fields which mostly takes place in the north-western part of the country is done by first locating the fields by satellite or simply by air reconnaissance, then sending a team of Marines to eradicate the cannabis plants.[6] One of its big seizures was in late October 2007, when Navy personnel in a joint operation with other agencies seized 23 tons of cocaine in the port city of Manzanillo, Colima.[7][8] Due to its actions, the Navy and in kind the Naval Infantry Force has risen in stature in the United States.[9]

Drug interdiction at sea is also part of the Navy's strategy to combat drug trafficking, this came to light when, on July 16, 2008, the Navy intercepted a 10-metre-long (33 ft) narco submarine travelling about 200 kilometres (120 mi) off the southwest of the state of Oaxaca; in a raid, Navy Special Forces rappelled from a helicopter on to the deck of the narco submarine and arrested four smugglers before they could scuttle their vessel. The vessel was found to be loaded with 5.8 tons of cocaine and was towed to Huatulco, Oaxaca, by a Navy patrol boat.[10][11][12][13][14]

Mexico sent marines to the U.S. in 2005 for disaster relief after Hurricane Katrina.

The shield anchor, crossed with the carbine, has been part of the Naval Infantry since 1823. The shield of the Naval Infantry, as today, is the essence of their integration into the meaning of heraldry. Examples are the gold trim, which gives nobility, seriousness and elegance; the Admiralty anchor, which symbolizes belonging to the Navy; and finally crossed muskets, symbolizing the weapons used by the first generation personnel of the Naval Infantry strengthening the country as a nation-state, free and sovereign. Together they represent the dedication to serve Mexico by air, land and sea. The color red has always characterized the Marines around the world.

The Iconography of the Marines of Mexico has developed a description of the standard as follows: at the center, the Marine Shield with its original colors, scarlet red cloth with gold-colored robes. In addition to being waved at official ceremonies, the Corps Standard (Estandarte) is present in all parades wherein the Corps takes part as a constituent branch of the navy proper. The corps standard is also present in the Corps Headquarters, all unit bases and in the Secretariat of the Navy.

After reorganization, the Marine forces were deployed under a new strategic operational concept with specific functions, including in the navy to the following Marine Corps units:[15]

• Two Amphibious Reaction Forces—deployed along the country's coastline, each comprising two Amphibious Infantry Battalions, Artillery Battalions, Amphibious Commando Battalions, Boat and Vehicle Battalions and Amphibious and Services Battalions.
• Thirty Naval Infantry Battalions are organized as follows:
  • 28 are organized into eight regional Brigades deployed as follows:
    • three on the Gulf coast: 1st, 3rd, and 5th each with four battalions,
    • four on the Pacific coast: 2nd with one battalion, 4th with five battalions, 6th and 8th with four battalions each, and
    • one (the 7th) in Mexico City with two battalions,
  • one Presidential Guard Battalion (24th Batallón de Infantería de Marina de Guardias Presidenciales),
  • one Paratrooper Battalions (BIMFUSPAR: Batallón de Infantería de Marina de Fusileros Paracaidistas),
• two small Commando Battalions: Batallón De Comandos Del Golfo (BATCOGO) and Batallón de Comandos Del Pacífico (BATCOPA),
• Three Special Forces Groups: FESGO (Fuerzas Especiales del Golfo), FESPA (Fuerzas Especiales del Pacifico), FESCEN (Fuerzas Especiales del Centro)
• one Naval Police Battalion,
• 24 Marine (National Service) Battalions for National Service personnel, raised recently, plus 1 Marine Regiment (National Service)

There are two Marine Amphibious Groups (the Gulf and Pacific), which have replaced the two Reaction Amphibious Forces, whose mission is the defense of national coastlines against any conventional aggression. Each has a total manpower of 3,000 men. Both are composed of two Amphibious Battalions of Marines, a Battalion of Marines Commandos, a Marine Artillery Battalion, an Amphibious Vehicles and Vessels Battalion, which includes 12 armored APC-70, and a Service Battalion.

The 24th Marine Battalion "Presidential Guards", created in 1983, is responsible for providing security to the president. It is quartered in the Mexico City, like the BIMFUSPAR (Marine Parachute Fusilier Battalion).

Finally there are 3 Marine Special Forces Groups (Strength, Spirit and Wisdom is their motto). The FESGO (Special Forces Gulf) and the FESPA (Special Forces Pacific), both destined for missions in support of the then new Amphibious Forces Reaction In 2008, formed the FESCEN (Special Forces Center), based in Mexico City, whose purpose is to provide the High Command Headquarters a grouping of special forces mission critical. While FESGO and FESPA have an effective of 220 marines each, the FESCEN has less than 160 personnel.

The Marine Parachute Battalion is an elite force, which is the strategic reserve of the High Command of the Mexican Navy for high impact operations and emergency. The organizational and operational needs motivated the creation of BIMFUSPAR in 1992. The new unit was championed by then-President Carlos Salinas de Gortari, on June 1, 1994. The Battalion is divided into three Marine Paratrooper Rifle Companies, a Weapon Support Company and a Command Group. The Company Headquarters and Services is integrated into the grouping of services 7th Marine Brigade, which belongs since 2010.

Each Marine Battalion has three Marine Infantry Companies, a Company of Support Weapons (mortars, rocket launchers and machine guns) and Services. Each Company has three Sections, each of three Platoons, which are themselves composed of thirteen elements in three Squads of four men under the command of a Third or Second Master. The Squads are formed by a Corporal Squad Leader, a rifleman grenadier armed with M16A2 and M203 40mm grenade launcher, a submachine gunner with a Colt RO 750 LSW 5.56 mm. and a rifleman with a standard M16A2. The organization of a Platoon at three Squads, a Section in three Platoons and a Company into three Sections responds to the need in any case with the three decisive factors in combat: assault element, the support and security.

Fuerzas Especiales (FES), (Special Forces), is a Special Operations Unit of the Navy officially established in late 2001.
