In modern usage, Armour, or the armoured is also a heavily armoured military force or organization, such as heavy infantry or heavy cavalry (as opposed to light infantry or cavalry).

A tank is characterized by heavy weapons and armour, as well as by a high degree of mobility that allows it to cross rough terrain at relatively high speeds.
Thin plates of spaced armour, steel mesh "RPG screens", or rubber skirts, were found to cause HEAT rounds to detonate too far from the main armour, greatly reducing their penetrating power.
Explosive reactive armour, or ERA, is another major type of protection against high explosive antitank weapons, in which sections of armour explode to dissipate the focused explosive force of a shaped charge warhead.

 Sloped armour - Slopedarmour
For a given normal to the surface of the armour, increasing armour slope improves the armour's level of protection, while for a given area density of the armour the protection can be either increased or reduced by sloping, depending on the armour materials used.
The LOS thickness is equal to the armour's normal thickness times the quantity one divided by the cosine of the armour's inclination from the vertical.
Sloping armour can cause additional protection-enhancing effects such as shattering of a brittle kinetic energy penetrator, but in thick homogeneous plates a long-rod penetrator will, after initial penetration into the armour's LOS thickness, bend toward the armour's normal thickness and take a path with a length between the armour's LOS and normal thicknesses.

 Tank
Protection is the amount of armour, the type(s), how it is arranged (e.g., whether it is sloping or not), and which areas are given more protection (e.g., the turret and tracks) and which receive less (e.g., the rear of the chassis).

Although weapons systems and armour continue to be developed, often at very high cost, many nations have reconsidered the need for such heavy weaponry in a period characterised by unconventional warfare.

Since then, other forms of armour, incorporating empty spaces and materials such as ceramics or depleted uranium in addition to steel, have been developed.
The term is used currently as RHAe (Rolled Homogeneous Armour equivalency) to give a rough estimate of either the penetrative capability of a projectile or the protective capability of a type of armour which may or may not be steel.

It was not uncommon for a man in armour, mounted on a horse, to ride up closer to the enemy, in a tactical manuever called "The wheel", and discharge his hand-cannon or pistols right into the faces, or coverage gaps in the armour of the adversary at close range.

Rolled homogeneous armour, or RHA, is a theoretical basic type of steel plate, used as a baseline to compare the effectiveness of military vehicle armour.
The more recent term RHAe (Rolled Homogeneous Armour equivalency) is used when giving a rough estimate of either the penetrative capability of a projectile or the protective capability of a type of armour which may or may not be steel.
Because of variations in armor shape, quality, material, and case-by-case performance, the usefulness of RHAe in comparing different armour has been described thus: "Using RHA equivalencies to measure the protective capacity of armour is a lot like weighing a pig in Iowa.

While tanks are expensive to operate and logistically demanding, they are among the most formidable and versatile weapons of the modern battlefield, both for their ability to engage other ground targets and their shock value against infantry.
Without such support, tanks, despite their armour and mobility, are vulnerable to infantry, mines, artillery, and air power.
Although weapons systems and armour continue to be developed, many nations have reconsidered the need for such heavy weaponry in a period characterised by unconventional warfare.

This technique of estimating the protective capacity of armour by calculating how thick rolled steel would have to be (in millimeters) to afford the same degree of protection has been illustrated by some with the following: "Using RHA equivalencies to measure the protective capacity of armour is a lot like weighing a pig in Iowa.

 Sloped armour - Wikipedia, the free encyclopedia
On the other hand, armour can be sloped to remove internal volume that would go unused and reduce the vehicle's mass.
The cause for the increased protection at a given normal thickness is the increased line-of-sight (LOS) thickness of the armour, which is the thickness along a line parallel to the oncoming projectile's general direction of travel (horizontal or vertical).
Research into the effects of sloping armour plate was first conducted in the 1930s by the French SOMUA, and by the Soviet tank design team of the Kharkov Locomotive Factory.

The expression 'rolled homogeneous armour' is used as a measure of the ability of a penetrator to defeat armour.
Usually measured in millimetres, the rolled homogeneous armour can be used to assess one type of armour against another, i.e., spaced armour and monoblock (solid) armour.
The armour produced by this method is known as Rolled Homogeneous Armour (RHA) and is used as the current standard of comparison for protection levels offered by other materials.

 'Smart' payloads offered for Russian air-launched rockets - Jane's Military Aerospace News   (Site not responding. Last check: 2007-10-21)
Intended for use against point targets such as armoured fighting vehicles, the new 'smart' rockets require the target to be illuminated by a helicopter-mounted or ground-based laser designator.
Developed around half a century ago, and first fielded in the 1950s, the S-5 (57mm) unguided rockets were intended to provide the former Soviet Union and its Warsaw Pact allies with a family of folding-fin unguided rockets for air-to-air and air-to-surface applications.
According to Ametech, the use of guided payloads increases of cost-effectiveness of the 57mm, 80mm and 122mm rockets by a factor of 3-4, and reduces the number of rockets which must be fired in combat by a factor of 50 or more.
