Here are my notes that I used for this video:
I think a good place to start would be defining what is reinforcement range. If we look closely here we will see that before we start this fight a red dashed line appears 3 hexes around it tell you, and understanding how it works will not only help you play better against the AI but also against human players.
Reinforcement range is a new mechanic to aow games, and so far I really like how it simplifies unit movement on the strategic layer. I am really excited to try it out more in multiplayer, which in case you did know I am hosting and streaming an aow4 mp on Saturdays, so I hope to see you there.
Use reinforcement range to save movement points (Post may 9th)
Keeping a single scout in an army, allows you to make the most out of your slower units movement, because scouts have more movement points and it is easier for them to change course.
It also allows you to send the scout where you want to go to go with the whole stack to get vision without committing the whole stack’s movement points (scouts also get bonus vision compared to other units I think).
I would move it 1 or two hexes at a time.
If you want it can also split off to start a fight that otherwise would be out of range for 1 turn.
Once you have more than 12 units traveling together, you only need to engage with either a single mobile unit if you only have 2 stacks with of other units (12 others plus the engager) or a mobile stack (of 6 units) that can engage an enemy with two others other full stack within reinforcement range
Use the fact that Spawners don’t reinforce to take fights earlier
Infestations do not support the stacks they spawn if you fight them within their reinforcement range
Cities cancel reinforcement, so you can use this to get easier fights (not ideal for mps)
If you or an enemy is within a 1 hex radius of a city center then they won’t engage in fights that are within its reinforcement range, which you can take advantage of if you have mobile stacks.
