platoon level, a mechanized infantry squad consists of nine infantrymen, in which seven members are dismounted during combat. Infantry squads vary in composition based on the type of combined arms battalions. Medium and light infantry squads equip reusable rocket launchers to improve anti-armor and anti-fortification capability, whereas heavy infantry squads have no squad-level rockets, instead relying upon fire support from the firepower platoon, or their own ZBD-04A infantry fighting vehicle. Weapons Individual and crew-served weapons The standard issue rifle of PLA infantrymen is QBZ-95/191 chambered in proprietary 5.8×42mm, and the sidearm is QSZ-92 chambered in 5.8×21mm DAP92. Vehicle crews are equipped with QBZ-95B short-barreled carbine. The QCW-05 is a 5.8 mm submachine gun used by special forces and non-combat personnel. Sharpshooting is provided by the QBU-88/191 marksman rifle and QBU-141/202 sniper rifle. Indirect fire is provided by the QLG-10 grenade launcher. QBS-09 combat shotgun is issued for door breaching and close-quarters battle. The QJB-95 serves as the squad automatic weapon with its 75-round drum magazine. PF-89, PF-97, and DZJ-08 disposable rocket launchers could be distributed on an ad hoc basis to infantry squads for direct-fire applications. Specialized fire support weapons, often equipped with dedicated rocketeers, or members of the firepower platoons, include the HJ-12 anti-tank guided missile, PF-98 rocket launcher, the QLZ-87 and QLZ-04 35 mm automatic grenade launcher, the QBU-10 anti-material rifle, QLU-11 sniper grenade launcher, QJG-02 anti-air machine gun, QJZ-89 heavy machine gun, and the PP-89/93 60 mm mortar. Infantry equipment and uniforms In 2014, the cost to equip a single Chinese soldier is about 9,400 yuan (US$1,523). The standard kit includes Type 07 camouflage uniforms, helmet, tactical vest, gas mask, backpack, first-aid kit, infantry weapons, woven belt, rain cap, camouflaged uniform, kettle, and combat boots. However, regular infantrymen rarely use the issued body armor stored in the armory. Prior to 2015, only special operation detachment and soldiers in the active mission were equipped with body armor. The infantry equipment such as heavy body armor, personal radio, and knee pads has been seen in the standard kit in 2015 when PLA are deployed into high-risk areas, as observed for units participating in UN Peacekeeping and counter-piracy operations. The PLA has started to procure body armors for soldiers on large scale since March 2020, with 1.4 million body armor on order, which includes 930,000 units of plates for universal bulletproof vests and 467,000 units of plates for an enhanced
