(Imaginary) Standing army tactics in 15th century Europe-like setting

by PULLUP_KRWA

Hi, I'm working on a fantasy book and trying to keep it at least somewhat realistic, hence the following situation.

Two powerful states, A and B wage war on each other. The technology level is equal for both, approximately at the level England and France had during the Battle of Agincourt (also no magic, dragons or any other supernatural stuff). A brings a standard feudal army - peasant levies and knightly cavalry. B, however, has a standing army of professional soldiers.

Would there be any differences in the composition of the fighting forces stemming from the difference in their "nature"? Would about their tactics in battle?

Thanks a lot for your input!

Hi there - we're happy to approve your question related to your novel, and we are happy for people to answer. However, we should warn you that many flairs have become reluctant to answer questions for aspiring novelists, based on past experience: some aspiring novelists have a tendency to try to pump historians for trivia while ignoring the bigger points they were making, while others have a tendency to argue with historians when the historical reality does not line up with what's needed for a particular scene or characterization. Please respect the answers of people who have generously given you their time, even if it's not always what you want to hear.

Additionally, as amazing as our flair panel is, we should also point out that /r/AskHistorians is not a professional historical consultation service. If you're asking a question here because you need vital research for a future commercial product such as a historical novel, you may be better off engaging a historical consultant at a fair hourly rate to answer these questions for you. We don't know what the going rate for consultancy work would be in your locality, but it may be worth looking into that if you have in-depth or highly plot-reliant questions for this project. Some /r/AskHistorians flairs could be receptive to working as a consultant in this way. However, if you wish for a flair here to do this work for you, you will need to organize this with them yourselves.
