Achaemenid Sparabara

[MrSki]

I've just been looking at the 2023 list and have a suggestion:
Persian Sparabara. 2/3 rear rank 1/3 front rank.
Front rank Formed Flexible, Avg, Protected, short spear, sheild cover and shoot, shieldwall.
Rear Rank Formed Loose Avg protected, experienced bow

Immortals go formed to drilled and exp bow to skilled
Applebearers go formed to drilled, Avg to superior and exp bow to skilled.
Special rule Sparabara can't count sheild cover to flank or rear.
Used in either 6 or 9. So 2front 4 rear or 3 front and 6 rear.

Maybe even have all the bow as unprotected. At best the 9 rows of bow behind the spear men with the spara had linen armour and no real sheild in most accounts I've read.
Maybe only have the immortals bow as protected, these are often depicted with a shield.

I believe this would more accurately represent them and give them a bit of bite initially then become quite squishy after a prolonged engagement, once the front rank gets stripped away. This also seems to be backed up by many accounts including herodatus.
