Agreed that the HW would be evens in the melee phase (assuming they managed to stay steady, and both were graded average). However, spear-armed troops would do even better in the melee phase if they stayed steady, and if disrupted would be no worse than disrupted HW armed troops. If the chariots didn’t disrupt the infantry then they’d break off and have another crack in their next impact phase.

Well we will think on it a bit more. Thanks.
It would be difficult to equate 1 chariot with 80 infantrymen – unless they were mob or MF with no combat capabilities (which you may be considering)! However, as T’ai Kung states, in difficult going 1 chariot is worth only 40 infantrymen, i.e. they are only half as effective. Therefore, instead of looking at absolute numbers perhaps we should look at relative effectiveness in different terrain, which I will have a (probably cack-handed) attempt at.
Measuring the chariot’s efficacy as the ratio of expected average chariot hits inflicted to average hits received (assuming both are steady at impact), with four superior chariots (no extra combat capabilities) attacking a block of 8 average infantry 2 deep:
MF with spear:
Open 1.17 (impact) 0.78 (melee) 1.56 (melee, infantry disrupted)
Uneven 0.58 (impact) 0.58 (melee) 1.17 (melee, infantry disrupted)
Rough 0.39 (impact) 0.39 (melee) 0.78 (melee, infantry disrupted)
HF with heavy weapon:
Open 1.75 (impact) 1.17 (melee) 1.56 (melee, infantry disrupted)
Uneven 1.17 (impact) 1.17 (melee) 1.17 (melee, infantry disrupted)
Rough 0.78 (impact) 0.78 (melee) 0.78 (melee, infantry disrupted)
MF with heavy weapon
Open 2.33 (impact) 1.17 (melee) 1.56 (melee, infantry disrupted)
Uneven 0.88 (impact) 0.88 (melee) 1.17 (melee, infantry disrupted)
Rough 0.58 (impact) 0.58 (melee) 0.78 (melee, infantry disrupted)
Note that the above figures don’t take account of potential for base loss in the impact phase for the subsequent melee.
It comes down to what degree you want the terrain to affect the chariots versus infantry – T’ai Kung reckons chariots are half as effective in difficult terrain, whereas Chao Cuo reckons that they are 20 times less effective! Looking at the above figures, at impact they are 3 times less effective against MF spear in rough compared to the open, 2.2 times less effective against HF/HW, and 4 times less effective against MF/HW. The respective figures for melee are 2, 1.5 and 2 times less effective. You could try and factor in the MF’s greater likelihood of going disrupted (or even fragmented) against mounted in the open, but this would increase the disparity between performance in the open versus that in terrain. In any case, the MF/spear’s melee performance is no better than HF/HW if disrupted, and much better if not. Of course if you put portable obstacles into the mix then the chariots would probably be screwed whatever terrain they attacked in!
In addition to this, if the interaction between ‘short weapons’ and ‘long weapons’ alluded to in Chao Cuo’s memo were to be taken into account we’d have to think about how the infantry above would cope with, say MF swordsmen. MF with spear could be expected to beat MF swordsmen in all terrain types. HF/HW would have a significant advantage in the impact phase in the open, which would decrease in uneven/rough terrain, but would be at a disadvantage in the melee phase in terrain. Although I haven’t been able to find much reference to interactions of different infantry types, the fact that infantry are often divided into ‘strong crossbows’, ‘long weapons’ and ‘short weapons’ (among others) in many texts suggests that they had their uses in different circumstances.
I think that on balance the HF/HW combination better reflects long-weapon interactions with both chariots and other infantry types. However, if you aren’t too fussed about the latter, then the MF/Spear combo will give a very clear separation in the performance of chariots in the open and in uneven/rough terrain, at least in the all important impact phase.
