Possible error in Bk1, L32 (Spring and Autumn Chinese)

[arnimlueck]

I have a suspicion that there is an error in List 32 in the section "Only from700 BC:"

There is a list entry that i already part of the errata, the corrected version is:
Archers - Irr Ps (O) @ 2AP [can support Bd(F)] or Irr Bw (I) @ 3AP  8 - 24

These are the only Psiloi available in the list. In the text below it states that Ps(O) can support Pk(F). For this tactic mentioned in the text I recall at least two battle accounts that would motivate this rule. But I do not know any occasion were skirmishing arches are reported to support "picked troops". I am aware that the definition of these "picked troops" is a bit vague because no historical account states precisely what these troops were. But I always assumed that most separations of standard infantry that were to conduct a specially timed attack apart from the main body would qualify.

If that interpretation is correct, I think the line on the archers actually should read
 Archers - Irr Ps (O) @ 2AP [can support Pk(F)] or Irr Bw (I) @ 3AP  8 - 24

Does anyone know of a battle that motivates the Ps(O) to support Bd(F) and Pk(F)?

And just because it came up in a discussion here: i do not know of any account either that would motivate Ps(O) to support the eralier (pre 700 BC) Tiger Guard. It just came up in the discussion because it would benefit the guard so nicely. But I have only read through few accounts of the earlier period.

If there is any more insight to read through the roles of these archers I would be happy if anyone to point me to the battles that motivate the list.

Actually Barritus mentioned this oodity in the "Some errata" thread but it was never answered or discussed
