The PLL-05 is a Chinese self-propelled gun-mortar in use by Chinese mechanised infantry formations. Conceptually it is similar to the Russian 2S23 “Nona-SVK” (the turret and weapon system of the 2S9 Nona mounted on a BTR-80 chassis) three of which China purchased for evaluation; at one time it was reported that China would purchase 100 of the Russian vehicles[2] however this failed to occur, nor does it appear that there was a formal transfer of technology to China. The Chinese system features a longer barreled weapon mounted on the Type 92 variant of the WZ551 armored personnel carrier.

The gun-mortar is a lighter and more compact artillery piece than the traditional gun-howitzer at the expense of maximum range, which has improved accuracy, a higher rate of fire, and having the capability of using direct fire in comparison to standard infantry mortars.

PLL-05自行迫榴炮是中國研發的一種迫榴彈炮。主要武器為1門120毫米後裝彈迫擊炮和1挺12.7毫米高射機槍，結合迫擊炮與輕型榴彈炮的特點，射程較遠彈道彎曲，相比大型自走砲容易佈署但火力和機動力又大於迫擊砲，可在密接前線提供小型砲兵支援，打地形遮蔽物後敵方目標。
