Chinese amphibious vehicles not actually amphibious #4331

Affected DBID(s)

Description of Problem

As of DB3K ver. 504, the following vehicles are missing movement values on water when they are clearly supposed to be amphibious. ZBD03, ZBD04, ZBD05, ZBD08, ZTD05, ZBL08, ZTL11, ZSL92, ZSL92A, ZSL92B, ZBD86, ZBD86A, PLZ07B, PLL05

Recommended Fix

Vehicles based off the ZBD05 chassis (ZBD05, ZTD05, PLZ07B) are designed for high speed open water amphibious operation (ie beach landings) with a max speed of 16knots.

Vehicles based off the ZBL08 Chassis (ZBL08, ZTL11) are capable of 5knots and can also operate in open waters given that they are in service with the PLANMC

the ZBD04 and ZBD08 can reach 10knots and 7knots respectively but is likely only used for fording operations as it is a PLAGF exclusive item

All other vehicles such as the ZBD03, ZBD86, ZBD86A, ZSL92, ZSL92A, ZSL92B, PLL05 have very limited fording capability at around 4knots

Though Im not sure if its modelled in the game, Bad sea states should entire prevent any of these vehicles from operating

PLZ07B https://www.militarytoday.com/artillery/plz_07b.htm *I assumed it has the same performance as the ZBD05 as it is the same hull and is denoted as 'amphibious'

I think this may be a game bug, the needed information to make them amphibious is present in the DB

Could the vehicle's propulsion need additional entries to allow an amphibious movement?

eg. ID 2946 VTA-903T (AAVP-7's) image image

Whereas ID ZBD-05 doesn't seems to have such entries. image

Yes, the engines need a -1 alt band like the ACV (Engine 2978).

Fixed DB3K 509.
