therother was kind enough to meet me on the multiplayer field of battle and let me shoot his poor Yari Ashigaru to pieces.
One thing we can conclusively state from this test is that 3000 corpses do not pile up over time.
After that morbid start, we can only go uphill! In a metaphorical sense, not in a totalwar sense because that would give us combat penalties. OK, research, right!
Hypothesis:
We had three test hypotheses:
1. Units in spearwall formation take less damage from arrows (shot frontally)
2. Units in loose formation take less damage from arrows (again shot frontally)
3. Samurai units of the same type as Ashigaru will take less damage from arrows
Method:
therother brought 10 units of Yari Ashigaru and 3 units of Yari Samurai to the battle. I brought 15 units of Bow Ashigaru.
It is hard to find a level spot on the two maps we tried, but we did manage to find a fairly flat spot covering about 100 yards. therother marched units to the same spot each time, and I replaced archers in the same spot, as they ran out of ammunition.
therother placed his General so that the unit being shot at was within the General's influence ring. This was not because he was nice -- it was so we would have more data to work with.
Finally, we ran between three and five test "mini-battles" per unit configuration, so the figures below reflect standardised averages over those tests.
Results:
Our results showed a fair bit of randomness, but some simple conclusions emerge. The following graph shows kills per volley.
Discussion:
Our hypothesis about the Spearwall stance was incorrect. They suffered the same loss rate as the non-stanced Ashigaru. The one difference was that Spearwall formation led to the unit routing an average of two rounds later than non-stanced Ashigaru.
Our hypothesis about units in Loose formation seems correct. They suffered an overall lower kill rate than either normal or spearwall formation Ashigaru. They also routed at a later time (2 rounds longer than Spearwall, 4 longer than non-stanced).
Finally, our hypothesis about Yari Samurai proved correct. They suffered the lowest casualties of all unit configurations tested. Not only that, but the standard deviation on kills was significantly lower than any other unit.
Conclusions:
1. If the enemy have archers, and you will be holding a position with standing troops, put them in loose formation. While this is one of the basic premises of command in TW, it bears repeating. This may be especially useful at bonus buildings on multiplayer maps.
2. Spearwall formation leads to higher morale and longer time on the battlefield, even when facing arrows. If you have peasant units, it may be worth it to put them in this formation at all times when not on the move.
3. The higher cost of Samurai units seems to be very well worth it. In some of our tests, the Samurai suffered half the kill rate of the Ashigaru.
Further Research:
1. The longer staying power of Spearwall formation needs to be studied in more detail. It could be that we simply had lower kill rates those last few rounds, and therefore the troops didn't have the "fast kills going on" morale penalty.
2. The stable kill rates with Yari Samurai deserves more attention. Does this hold up in an infantry vs infantry battle?
OK, that's enough text for one day!
