Ancient texts of interest but not online?

[Roger Pearse]

I wonder if there are any ancient texts that people can think of, which are of great interest for Roman military matters, or are regularly referred to, but are either not translated into English or not online?

The context is that I sometimes commission translations of ancient texts, and I just realised that (a) there must be some in this area and (b) that nothing comes to mind!

All the best,
