Turn 11:
Shelling from the Chinese artillery has become more accurate, sinking two more boats to the western approach, one with an engineer section inside the other with a sniper. Those assault units have to row fast if they want their lives. Soviet artillery continues to suppress their adversaries, but the Chinese have a lot of tubes. On the eastern approach, amphibious vehicles also get their wheels wet (BAV-485, an amphibious soft-skinned vehicle), carrying more engineers. Although they can carry more men, the fact that their unarmoured makes me nervous. Spetsnaz units start clearing minefields and some of them decide go mortar hunting (isolated puffs of smoke are visible on the map...)
Anyway a few screenshots to show the situation:
The Eastern (actually northern in the map) avenue of approach. Assault boats and amphibious cars are visible, plus overwatching ISUs
The Western (southern on the map) avenue of approach. The surviving assault boats, plus a lot of smoke shows up. A PT-76 may be just visible, it is the one my scout teams discovered.
The Spetsnaz units and the mayhem they, the artillery and the overwatching ISUs caused.
