Mechanization hurts COIN forces

[Ken White]

So does this mean the the medieval and ancient distinction of "heavy infantry" and "light infantry".

That would work but being a traditionalist (when it suits... ) I'd go for Infantry (period) and Dragoons.

If so, this does have considerable merit. We'd have
"light infantry" with effective protected mobility to enable their light infantry mission - IMVs. "heavy infantry" optimised to operate with armour formations.

Change to:

Infantry, primarily foot mobile but able to quickly adapt to air or vehicle (including IMV) operations as the mission requires. Dragoons, primarily mounted in vehicles but prepared to dismount to provide close in protection for Armored formations and to provide limited range dismounted action on infantry like missions (added: ) as a component of Armored forces. The Armored force may be mounted in wheeled or tracked vehicles; the defining factor being their training and equipment aimed at highly mobile and predominantly mounted combat.

Armor also needs mounted engineer / pioneer types, specifically trained for the mission. I'm still searching for a name. Neither Drappers nor Sagoons seems to work very well...
