Between costing 20 production less, better comba modifiers, and the commando buff (+1 movement) they aren't bad units now in a vacuum. However they still suffer from the fact that you need to research military tactics and you can't hard build them. Military tactics doesn't lead to any other techs, and onyl gives access to certain military units and Huey. 275 science is a steep price to pay. I think they should look into reworking the tech tree a bit in this regard. That being said, its still a fun and flavorful unit and I will use them en masse when playing Norway, even if it's not the most efficient route to victory.
