The RPG-26 Aglen is a disposable anti-tank rocket-propelled grenade (RPG) launcher developed by the Soviet Union.

It fires a one-stage rocket with jack-knife fins, which unfold after launch.

The rocket carries a 72.5-millimetre (2.85 in) diameter high-explosive anti-tank (HEAT) single shaped charge warhead able to penetrate 440 millimetres (17 in) of armour, 1 metre (3 ft 3 in) of reinforced concrete or 1.5 metres (4 ft 11 in) of brickwork.

The RShG-2 (Russian: Реактивная Штурмовая Граната, Reaktivnaya Shturmovaya Granata, Rocket-propelled Assault Grenade) Aglen-2 (Аглень-2) is a RPG-26 variant with thermobaric warhead.

RShG-2 is heavier than the RPG-26 at 3.5 kilograms (7.7 lb) and has a reduced direct fire range of 115 metres (377 ft).
