Army Rangers Duties

The foundation of Ranger operation is performing as a quick "shock troop" -- one capable of carrying out surprise strikes . But how they get to their strike zone, what they do there and what command is calling the shots varies widely by operation.

Since they're Airborne graduates, Rangers often parachute to the designated insertion area. But they're also trained for other types of insertions -- or means of getting soldiers quickly and quietly behind enemy lines -- like a small boat in a swamp or down fast lines (ropes lines that allow a quick descent) from the sides of a helicopter. Once on the ground, their operations take many forms. In a strike situation, the Rangers' archetypal operation is the seizing of an airfield.

They're also extremely versatile and can easily move from a special operation into a conventional one, once the initial mission is fulfilled. For example, if the Rangers' mission is to take an airfield, they may parachute in, eliminate any threats, take control of the airfield and signal that the mission is accomplished. When conventional forces move into the secured airfield, Rangers can link up with them, moving onward as part of the larger conventional-fighting force.

These kinds of strikes and raids are called direct-action operations, and they can eventually get pretty loud due to the gunfire that erupts. There's another type of operation for which Rangers are suited -- reconnaissance, or recon. Recon is Ranger tradition, born from the Colonial scouts and honed by the long-range patrols in Vietnam. All Rangers are taught recon, but there's also a small specialized group of Rangers extensively trained for scouting and recon -- the Regimental Reconnaissance Detachment (RRD).

Created in 1984 as part of the Ranger expansion, the RRD consists of three, four-man teams of seasoned scouts who can survive for up to five days behind enemy lines in a silent state with minimal movements [source: SpecWarNet]. There are only 12 of these soldiers for the entire 75th Regiment, and each team is attached to one of the three battalions. RRD Rangers are asked to confirm or deny existing intelligence, place surveillance equipment in enemy territory, report on troop movement and call in strikes or acquire targets. In some very uncommon circumstances, these teams may be called upon to carry out specific direct-action strikes, but for the most part, their main objective is to come and go undetected.

Rescue missions are also tailor-made for Rangers. These missions are often a combination of direct action and reconnaissance. Rangers must first confirm intelligence concerning the whereabouts of a lost troop or prisoner of war (POW), and in many cases must engage the enemy with fire to gain control of their objective. Rangers are suited for rescue missions because of their ability to get in and get out, their endurance for long-distance movement, their ability to remain undetected and their light-infantry capabilities. All this means that Rangers can get to places that most others can't.

Perhaps the most notable Ranger-rescue mission was carried out by troops led by Colonel Henry Mucci. In the next section, we'll learn about Mucci's Rangers and some other notable Ranger operations.

Army Rangers Notable Operations

The bloody Allied invasion of Normandy, France, in World War II is considered to have been successful largely because of the actions taken by the Rangers. The invasion proved to be a particularly deadly one -- Allied troops suffered as many as 10,000 casualties in just a few days. The German positions were well-stationed, and machine gunners perched on the cliffs overlooking the sea had a vista of the entire beach.

It was here that the Rangers' motto was born. Aware that perhaps no one else could break through the German front, Brigadier General Norman Cota shouted to the 5th Battalion stationed on the beach, "Rangers, lead the way!" The Rangers did just that, penetrating the enemy beachhead -- their foothold along the shore -- and literally climbing the cliff walls to reach and capture the German machine-gun nests, leaving open just enough space for the larger forces to enter [source: SpecialOperations.com].

World War II also gave the Rangers some of their largest losses. In Cisterna, Italy, the Rangers broke through the Axis lines, only to have the front collapse behind them, blocking Allied forces from moving in and leaving the Rangers trapped. Almost three battalions were lost in that battle, and it was after this that the Rangers absorbed the 5307th composite force, nicknamed Merrill's Marauders -- the group that had recaptured Burma Road from the Japanese -- to replenish the ranks [source: SpecialOperations.com].

In the Philippines during World War II, Rangers led by Colonel Mucci executed a raid on a Japanese prison camp that held Allied prisoners of war. These prisoners were scheduled for death once the Japanese no longer had use for the camp. Mucci, along with his Rangers and Filipino guerrillas, attacked the prison camp, freeing 500 prisoners of war, killing 200 Japanese soldiers and fleeing into the jungle, carrying some POWs on their backs for as long as two days [source: SpecialOperations.com].

Rangers have also contributed to peacetime missions, like in Grenada during Operation Urgent Fury in 1983. After an airborne insertion, Rangers converged on a medical facility where Americans were trapped by the violent uprising within the Caribbean island nation. Rangers rescued the Americans and helped quell the uprising. The mission was declared a success and, as a result, the next year the 3rd Battalion was formed [source: GlobalSecurity.org].

The Rangers' presence was also noted in Panama in 1989. All three of the Ranger battalions fought together during the invasion of the Central American country to remove the dictator, General Manuel Noriega. As part of Operation Just Cause, Rangers took airfields and airports -- in true Ranger fashion -- and engaged the Panamanian Defense Force in firefights [source: GlobalSecurity.org].

The Rangers have also survived defeats. Operation Eagle Claw -- the 1980 special operations mission tasked with releasing 66 American hostages in the embassy in Tehran, Iran, -- failed and left eight of the force dead. And in Somalia, during Operation Restore Hope, the special operations force, of which the Rangers were part, suffered 18 deaths in as many hours [source: SpecialOperations.com]. The firefight that took place is recounted in the book and film, "Blackhawk Down."

Despite their losses, the Rangers have always had a big impact with minimal numbers. In World War II, for example, out of the 15 million Allied troops, only 3,000 were Army Rangers [source: World War II Army Rangers].
