Oh yes - another reason not to have these scouts or whatever 'commanders' in the AI forces.
They move at different rates and so the AI will never be able to keep any such platoons in a group - they will fall behind or kamikaze out front (e.g. a jeep commanding slow SP-AT). or they will obey different AI rules - so an APC with a commander on foot would charge forwards ("I am a loaded APC") while its SP-ATGM try to hold back for long range shots ("we are missile anti-tank")
.
So the commanded units would soon be out of command control, either by distance or by decapitation of the kamikaze commanders...
There was no real code for keeping platoons together in the original SP AI code - now they do - so if the platoon commander is charging out in front (or holding back) then the faster/slower units may be 'pegged' to him, or in a rush to join him if he kamikazes out in front). SP platoons work best if all are similar - there is code for APC+infantry formations now, but otherwise there is nothing for mixed formation speed (or type of unit), e.g using the slowest for all. SP AI units still really are individuals, with no concept of formation. Other than the 'try to blob onto the platoon commander, if you can' we added, anyway.
Another minor item is that the listing code looks at the unit class of unit 0 of each formation to decide where to place it on the purchase list - so an SP-AT platoon that gets a scout as unit 0 will display somewhere completely different from the pure SP-AT ones.
