Classical Indian is an army that looks especially good in 6mm. It is a powerful army in DBA, and can be very effective in DBM.

My usual Classical Indian DBA army is:
3 El (including general), 2 Kn (4-horse, 6-crew heavy chariots), 2 Cv (Indian cavalry of poor
quality), 4 Lb (Indian hereditary archers), 1 Bd (guardsmen, or hereditary javelinmen).
I use a buddhist stupa as my camp. This is slightly wrong for really early armies
(pre-Ashoka), but looks good. It is quite "clean", as is proper for very early
stupas.
This is a good mix of very powerful elements, able to handle most armies well.
