Help needed for the Bolo series

I have recently gotten some Bolo series books in pdf format but I can't figure out what is the order to read them. Some of the later ones seems to be missing the pages where this is usually written. I have tried looking up the authors wiki and Good reads but im still getting confused.

This is the list of books i have:

• Bolo!


• Bolo Brigade


• Bolo Strike


• Bolo Rising


• Cold Steel


• Honor of the Regiment


• The Unconquerable


• Old Guard


• Old Soldiers


• Compleat Bolo


• Last Stand


• Road to Damascus


• The Triumphant
