No idea if possible but in generated battles vs AI so no waypoints could it be possible in meetings AI advances to set up fast units further back or give them a delay before they start moving.

Just played vs Brits 5/41 N.Africa.
Troops & tanks arrived pretty much together as speed 8 for most tanks.
poor armoured cars more than 3 times as fast entered the turkey shoot several turns earlier due to being more than 3 times faster.

I seem to remember reading in a post somewhere that there is a bit of unit info that plays no part in the game anymore this could be used as a delay trigger say O-3 turns.
Realise lot of work if possible & would still not be perfect, map width terrain etc but still feel it would make a big impact vs AI.
Or if possible make them move at slower speed for first 3 turns
