Light Chariots?

When using Light Chariots ( not the light Barbarian Chariots)

I understand they have a fire range of 3 (not 2)
with a ranged fire of 2/1?

How many Blocks per unit two or three?

What is their CC value?

any other special features?

I understand they have a buy value of 4

any help or comments?
Thanks

Hi Arthur,
just received and answer directly from Mr Tony Curtis.

In the 3rd Edition rules, we did away with Light Chariots because we never used them.
The range error had become a distraction.

Just for info.
