Deletions:
Units 062 and 430: Type WZ 501 - China only got a few examples of the BMP-1 via Egypt in the late 70s, and these were used for reverse-engineering purposes.
Unit Name/Date Corrections
Units 056 and 434: Type WZ 501 - Really is "Type 86". Was accepted into PLA service in 1992; before then, only a few small batches had been made for testing.
Deletion
Unit 068: Type YW 309 - This was only a NORINCO prototype.
Unit Name/Date Corrections
Unit 063: Type WZ 501A - Really is "Type 86-I"; entered service in I think 1995~; give the PLA time enough to realize that the Type 86's BMP-1 armament won't cut it.

New Unit:
Type 86B: Basically take a Type 86 IFV and improve it for amphibious operations, mainly consisting of general overall detail changes, including an external swim vane (probably worth 1 point of armor on the frontal slope); and a modified outboard engine hung off the back. You also get a spiffy blue themed paint job. Currently being used by PLA Marine Corps as interim vehicles until they get the new Amphibious tank/IFVs.

New Unit:
Type 86G: The PLA is replacing their original Type 86s with this new version, which has an indigenious turret containing a 30mm cannon and HJ-73 ATGM launcher.

Unit Name/Date Corrections
Unit 058 - Type YW 531 - Really "Type 63A"; entered service in 1970, not 1967.
New Units: Apparently, in the early 1990s; the Type 63G and 63K improved variants (YW 531G and K) entered PLA service. No idea what was changed. Possibly improved road speed due to better engine?
Unit Name/Date Corrections
Unit 503 - YW 534 HJ-8 - Really "ZDF-89 HJ-8", entered service in 1990, not 1986
Unit Name Corrections
Unit 504 - YW 534 HJ-8E - Really "ZDF-89 HJ-8E"
Unit Name/Date Corrections
