Introduction

The BTR-70 is an armored personnel carrier of Soviet origin. The BTR-70 was developed in the mid 1970's to supplement the BTR-60 used by the Soviet motorized infantry. The BTR-70 was in turn replaced by the further improved BTR-80. The TAB-77 is a Romanian derivative of the BTR-70.

Layout

The design of the BTR-70 is largely based on the earlier BTR-60PB and can be considered a further improved version. The driver and commander are seated side by side at the front of the vehicle. The one man turret is installed just behind them. The infantry compartment is in the middle of the vehicle and can be accessed by doors fitted between the 2nd and 3rd roadwheel and from large hatches in the roof. The two engines are installed at the rear.

Firepower

The BTR-70 is fitted with the same armament as the BTR-60. The 14.5mm KPVT heavy machine gun is the main armament and a 7.62mm PKT machine gun is mounted as a coaxial weapon. The KPVT can be used against light armored vehicles, soft skin vehicles and infantry behind sandbags or within buildings. It is also more capable of engaging infantry at long range than the PKT. At the time of development most Western armored personnel carriers could be engaged, although nowadays protection against 14.5mm rounds is rather common.

Protection

The sloped steel armor protects the crew and infantry from small arms fire and shell splinters. Over the frontal arc there is protection against 12.7mm rounds. Overall the BTR-70 has a higher level of protection than the older BTR-60PB. An NBC system is fitted as standard, but smoke grenade launchers are not.

Mobility

The BTR-70 has a good mobility on roads and speeds of up to 80 km/h can be achieved. The off road capability is rather good as well, but cross country mobility is limited under certain conditions. The BTR-70 is fully amphibious and is propelled in the water by means of a single water jet. Two 120 hp gasoline engines provide propulsion.

Users

The main user of the BTR-70 was the USSR and large quantities remain in use with ex-USSR nations. Many Eastern European nations also acquired the BTR-70 and some developed their own versions. Unlike most Soviet equipment the BTR-70 was hardly exported to other parts of the world and thus the BTR-70 is very uncommon in Asia, the Middle East and Africa.

Variants

BTR-70

The BTR-70 is an armored personnel carrier that can be considered a further improved version of the BTR-60PB. It can be distinguished from the BTR-60PB by its reshaped nose and rear sections, different wheels, more distinct wheelbays and low mounted doors between the 2nd and 3rd wheel. Early versions were fitted with 115hp gasoline engines until the more 120hp gasoline engines were introduced. Several command and specialist versions have been developed, but these are rather uncommon.
