Played Hueishan Docks (BFP29) over a few VASL sessions. I was the (defending, then counter-attacking) Japanese.
This is a real meaty scenario. In a very crowded urban (BFP-made) map, the Chinese need to seize at least 6 of 10 buildings sitting along the docks. For this, they have more than 30 squads, almost two thirds of them elite, quite a few German-made weapons (mortars and an AT gun), and a lot of (flimsy, but still) AFVs. The Japanese start badly outnumbered (2 to 1 infantry-wise, but with no armor, with a full board length to defend), but halfway through, they get a significant boost in the form of their own armor and, very significantly, 10 squads, half of them elite, with no less than 3 DC and 3 FT. These reinforcements on the west end side of the docks, so while they get to push back the Chinese there, the eastern end is unreachable.
So, my initial plan as the Japanese was to delay the Chinese as much as possible, definitely dying in place if needed, until the reinforcements could come and stiffen up the defense. I did setup a HIP half-squad in the upper level of one of the victory buildings just in case.
My opponent (Cyril) surprised me by attacking only from the east (where the Chinese have less ground to cover to reach the docks, sure), trying to use numbers to move from east to west along the docks - I was expecting a more spread out attack all along the map, especially considering the number of troops available.
The part of the Japanese OB that was sitting in the way of the Chinese attack did just what they were expected to do: they slowed them down, a lot, and they died in place, all of them. Several of the Chinese AFV were killed by the small 37* INF SW-gun, despite their typically small size and its inability to get Acquisition (and the rest of them were plagued by their B11 weapons - but that was a problem shared by both Japanese and Chines weapons, with very few exceptions). The part of my OB that didn't stand in the way of the Chinese attack could fall back in the direction of the docks, and mostly made it unharmed.
Overall, by the start of Japanese turn 4 when the reinforcements entered, the Chinese had only managed to grab 3 of the victory buildings (and actually, only 2, 'cause I still had my HIP HS in the easternmost - Cyril could have Mopped Up or Searched but forgot to do so). More importantly, his truck-towed AT gun and truck-carried German mortars were still not in place, so that my mighty Type 89 CHI-RO with their tough 1 AF (2 on turrets) and huge 57* guns could move to the rescue with relative impunity. (It helped that the Chinese OBA failed to place even a SR prior to that)
Overall, the Chinese attack was stalled at roughly half of the docks, with 5 buildings in Chinese hands (if they had taken the time to wipe out my hidden HS), but the arrival of the reinforcements made it impossible for them to get any further. The mortars and AT gun, once in place, wiped out most of the Japanese armor, but it was too late and my opponent conceded after his 7th turn (out of 8).
In the after-game discussion, we agreed his massed attack from the east was probably not the best plan. The Chinese have enough troops and vehicles that they can afford to send some from the north; if they maybe don't get to capture the whole docks, at least it should let them capture the buildings north of them so as to prevent the Japanese reinforcements from rushing to the rescue.
Overall, it was a fun game, with lots of little-used vehicles on both sides (this was my first game vs the Chinese in, well, at least 20 years I think)
