I'd start with small sized battles, infantry only at first and then work up to combined arms. There is a scenario in the CW module called 18 platoon which is a Probe using a platoon against a German OP, good for honing the skills.
You could also do a "play-along" with one of the YTers out there. @Haplesshas a playlist where he went through The Road to Montebourg campaign so you could try and emulate those tactics?
Also I'd recommend reading through Bil's blog, it's a great reference and teaching aid: https://battledrill.blogspot.com/
