The Mortier de 81mm léger long renforcé (LLR 81 mm) is a mortar used by the French Army, manufactured by Thales. Introduced in 1997, it is the latest iteration of the TDA 81 mm light mortar family.
== Description == The original TDA 81 mm was designed in 1961 (hence the MO-81-61 designation). Since then, three variants have been fielded:
the 81mm LC or MO-81-61-C (Léger court, "light short"), with a 1.15-metre barrel; the 81mm LL or MO-81-61-L (Léger long, "light long"), with a 1.55-metre barrel; the 81mm LLR (Léger long renforcé, "light long reinforced"), paratrooper version with a 1.55-metre barrel. The LLR 81mm is composed of a base plate, a barrel comprising the breech, and a bipod. It can use the same pointing optics as the MO-120-RT-61. The LLR 81mm can be parachuted either piece by piece, in a kit comprising a dismantled weapon and ammunition, or in larger crates comprising several weapons. The barrel was reinforced so as to allow firing of all existing 81 mm mortar ammunition.
