Some time ago someone in Colosseum mentioned in passing how he'd gone about converting the Brit Light Chariots and their BI equivalents from ahistorical archers to rather more historical javelin-throwers, and kindly also explained how to go about it. Alas, I didn't think much more of it at the time, and it rather seems like the thread has gone the way of the Dodo by now.

I'm mainly curious about what steps are necessary to swap the bow-toting crew to javelin-toting ones, and on the side how you edit the number of crew members if needed. Thanks in advance.
