just leaves the prec cavalry
Can you give me a list of units for those? I can possibly work something out. Was trying to find a cavalry with prec_javelin but could not find any. Or is it the havy_cav_javelin the prec ones?

I think the issue if they still don't work is they need the just a bit more top speed so all are in range before charge. But if you can tell me unit names I can find out.
