Tank machine guns
The 5.8 mm QJT is a Chinese coaxial machine gun based on the QYJ88 machine gun. Upon its introduction in Update "Ground Breaking", the QJT was the first machine gun in the game chambered in an intermediate cartridge.
The QJT is based on the QJY88 General Purpose Machine Gun (QJY88式通用机枪). The QJT is chambered in the 5.8x42 mm DPB88 "Heavy" cartridge (88式5.8毫米"重型"子弹).
Like many rifle-calibre machine guns found on tanks, the only option for QJT is the default belt that comes with the vehicle, sharing the same penetration as previous 7.62x54 mmR rounds or NATO's 7.62x51 mm rounds; which again is only good for gunning down exposed crew of enemy vehicles.

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.
As a variant of QJY88 GPMG, the QJT found on vehicles has an electrical trigger to serve as a coaxial machine gun. Like many of its analogues like the M240, SGMT, PKT (and its Chinese brother Type 86), they are only good for gunning down crews of exposed vehicles; only in very rare or extreme cases can it penetrate some very thin armour. Using the QJT as a last ditch weapon to gun down aircraft is also possible but only in rare occasions.

The trend of smaller-calibre rifle cartridges went on since the mid 1960s with the introduction of M16 with using 5.56x45 mm NATO rounds, then later AK-74 with Warsaw Pact 5.45x39 mm rounds. These were seen by the PLAGF in the 1970s, which was seeking for the development of smaller-calibre rifle cartridges; in 1979, PLAGF started their development of 5.8x42 mm rounds and later in 1987, DBP87 passed for certifications and was first used on the rechambered version of QBZ81 assault rifle- QBZ87. This 5.8 mm calibre was later used by various type of gun ranging from pistols, submachine guns (5.8x21 mm DAP92), as well as the selected cartridge for assault rifles since QBZ95 and light machine guns.
QYJ88, serving as a smaller-in-size alternative to the rejected Type 80 LMG (copy of PKM), was then saw as an alternative to the previous 7.62 mm coaxial machine guns in 2001 and was certified in April of 2004 which was first installed on ZBL08 family as QJT, with electrical-trigger for vehicular usage.
Excellent additions to the article would be video guides, screenshots from the game, and photos.
