A defensive fighting position (DFP) is a type of earthwork constructed in a military context, generally large enough to accommodate anything from one soldier to a fire team (or similar sized unit).

Tobruk type positions are named after the system of defensive positions constructed, initially, by the Italian Army at Tobruk, Libya. After Tobruk fell to the Allies in January 1941, the existing positions were modified and significantly expanded by the Australian Army which, along with other Allied forces, reused them in the Siege of Tobruk.

A foxhole is one type of defensive strategic position. It is a "small pit used for cover, usually for one or two personnel, and so constructed that the occupants can effectively fire from it". [1]

It is known more commonly within United States Army slang as a "fighting position" or as a "ranger grave". It is known as a "fighting hole" in the United States Marine Corps, a "gun-pit" in Australian Army terminology, and a "fighting pit" in the New Zealand Army.

In British and Canadian military argot it equates to a range of terms including slit trench, or fire trench (a trench deep enough for a soldier to stand in), a sangar (sandbagged fire position above ground) or shell scrape (a shallow depression that affords protection in the prone position), or simply—but less accurately—as a "trench".

During the American Civil War the term "rifle pit" was recognized by both U.S. Army and Confederate Army forces.

A protected emplacement or concealed post in which one or several machine guns are set up is known in U.S. English as a machine gun nest. [2]

During the fighting in North Africa (1942–43), U.S. forces employed the shell scrape. This was a very shallow excavation allowing one soldier to lie horizontally while shielding his body from nearby shell bursts and small arms fire. [3] [4] The shell scrape soon proved inadequate in this role, as the few inches of dirt above the soldier's body could often be penetrated by bullets or shell fragments. It also exposed the user to assault by enemy tanks, which could crush a soldier inside a shallow shell scrape by driving into it, then making a simple half-turn. [5]

After the Battle of Kasserine Pass (early 1943), U.S. troops increasingly adopted the modern foxhole , a vertical, bottle-shaped hole that allowed a soldier to stand and fight with head and shoulders exposed. [4] [6] The foxhole widened near the bottom to allow a soldier to crouch down while under intense artillery fire or tank attack. [4] Foxholes could be enlarged to two-soldier fighting positions, as well as excavated with firing steps for crew-served weapons or sumps for water drainage or live enemy grenade disposal.

Tobruks

The Germans used hardened fortifications in North Africa and later in other fortifications, such as the Atlantic Wall, that were in essence foxholes made from concrete. The Germans knew them officially as Ringstände; the Allies called them "Tobruks" because they had first encountered the structures during the fighting in Africa. [7]

Frequently, the Germans put a turret from an obsolete French or German tank on the foxhole. This gave the Tobruk enhanced firepower and the gunner protection from shrapnel and small arms.

Modern militaries publish and distribute elaborate field manuals for the proper construction of DFPs in stages. Initially, a shallow "shell scrape" is dug, often called a ranger grave, which provides very limited protection. Each stage develops the fighting position, gradually increasing its effectiveness, while always maintaining functionality. In this way, a soldier can improve the position over time, while being able to stop at any time and use the position in a fight.

Typically, a DFP is a pit or trench dug deep enough to stand in, with only the head exposed, and a small step at the bottom, called a fire step, that allows the soldier to crouch on to avoid fire and tank treads. The fire step usually slopes down into a deeper narrow slit called a grenade sump at the bottom to allow for live grenades to be kicked in to minimize damage from grenade fragments.

When possible, DFPs are revetted with corrugated iron, star pickets and wire or local substitutes. Ideally, the revetting will also be dug in below ground level so as to minimise damage from fire and tank tracks. The revetting helps the DFP resist cave-in from near misses from artillery or mortars and tank tracks.

Time permitting, DFPs can be enlarged to allow a machine gun crew and ammunition to be protected, as well as additional overhead cover via timbers.

In training, DFPs are usually dug by hand or in some cases by mechanical trench diggers. On operations, explosives, especially shaped charges ("beehives"), may be used to increase the speed of development.

Developing and maintaining DFPs is a constant and ongoing task for soldiers deployed in combat areas. For this reason, in some armies, infantry soldiers are referred to as "gravel technicians", as they spend so much time digging.

Because of the large expenditure in effort and materials required to build a DFP, it is important to ensure that the DFP is correctly sited. In order to site the DFP, the officer in charge ("OIC") should view the ground from the same level that the intended user's weapons will be sighted from. Normally, the OIC will need to lie on his belly to obtain the required perspective. This ensures that the position will be able to cover the desired sector.

<span class="mw-page-title-main">Anti-tank warfare</span> Science and Technology tactics based around countering and immobilizing tanks

Anti-tank warfare originated from the need to develop technology and tactics to destroy tanks during World War I. Since the Allies deployed the first tanks in 1916, the German Empire developed the first anti-tank weapons. The first developed anti-tank weapon was a scaled-up bolt-action rifle, the Mauser 1918 T-Gewehr, that fired a 13.2 mm cartridge with a solid bullet that could penetrate the thin armor of tanks at that time and destroy the engine or ricochet inside, killing occupants. Because tanks represent an enemy's strong force projection on land, military strategists have incorporated anti-tank warfare into the doctrine of nearly every combat service since. The most predominant anti-tank weapons at the start of World War II in 1939 included the tank-mounted gun, anti-tank guns and anti-tank grenades used by the infantry, and ground-attack aircraft.

The M10 tank destroyer was an American tank destroyer of World War II. After US entry into World War II and the formation of the Tank Destroyer Force, a suitable vehicle was needed to equip the new battalions. By November 1941, the Army requested a vehicle with a gun in a fully rotating turret after other interim models were criticized for being too poorly designed. The prototype of the M10 was conceived in early 1942 and delivered in April that year. After appropriate changes to the hull and turret were made, the modified version was selected for production in June 1942 as the 3-inch Gun Motor Carriage M10. It mounted a 3-inch gun M7 in a rotating turret on a modified M4 Sherman tank chassis. An alternate model, the M10A1, which used the M4A3 variant chassis, was also produced. Production of the two models ran from September 1942 to December 1943 and October 1942 to November 1943, respectively.

Infantry tactics are the combination of military concepts and methods used by infantry to achieve tactical objectives during combat. The role of the infantry on the battlefield is, typically, to close with and engage the enemy, and hold territorial objectives; infantry tactics are the means by which this is achieved. Infantry commonly makes up the largest proportion of an army's fighting strength, and consequently often suffers the heaviest casualties. Throughout history, infantrymen have sought to minimise their losses in both attack and defence through effective tactics.
