That's 65000 points US AI, 20000 China (me).
China buys around:
10 reservist infantry companies
30 Type 58 AAMG
15 WA021 155mms batteries
Lots of ammo trucks
10 Z-5 helos
Two tank companies, just in case
Strategy: Kill everything with cluster bombs.
Deployment: Infantry split between southern and northern flanks. Nothing in the center.
Some screens for the initial deployment:
Turn 1:
Initial bombardment takes out a few tanks across the map. The US has a prep bombardment as well and kills a few of my northern infantry. The AA guns are to turn out to be unnecessary as the US bought no air assets.
Turns 1-31:
Infantry advances. Machineguns snipe away at my flanks, killing several squads; acceptable losses. Enemy positions and mortars pounded with 155mms when spotted.
Northern flank:
Southern:
Turns 31-71:
US forces crumble under the red hordes. An Abrams company counterattacks from the south and is wiped out by artillery in two or three turns. Javelins and Stingers turn out to be the US' most effective combat unit, because they can see through smoke. At least they manage to hold the center objectives against a detachment sent from the southern front.
The helos load some AA guns and try to go around the northern flank to reach objectives out of reach of the infantry. All but one is shot down by Patriots, Stingers, and Javelins. That one lands on an objective only to hit a mine, killing the helo and its passenger.
Northern flank:
Center:
South:
Final score:
You can tell that I have a lot of time on my hands.
