I am not so sure about that. After all, if all you really wanted to do was to pound a planet flat then rebuild, why use ground forces at all? A Historic Lesson on that would of course be Mounte Cassino Abbey. The place was pounded flat, not once but three times. Yet it still had to be bypassed. (Remember Anzio?) It took four or five times to finally take it. Airpower can rain down quite a bit of destruction, and these days very accurate destruction, but it still can't take or hold ground. That is why we still have and will probably always have ground pounders.</font>[/QUOTE]Originally posted by Bhoins:

I'm not sure there would be that much need to fight in the artificial environments. These are relatively fragile places and probably very dependent on some form of outside support. The Imperium could probably compel surrender by using a combination of military and political tactics specifically targeted at denying the artificial environment what it needed to survive. I think fighting inside would be the last choice of all involved. One carefully targeted meson gun blast from a spinal mount would probably be enough to convince those in charge that the Imperium was serious about taking the place back and more than willing to destory it and rebuild it later if they needed to.
My point was about artificial environments that are dependant on some fundimental resource (such as air) to maintain survival. Those environments are very vulnerable to very specific presures. The German troops at Mounte Cassino Abbey could have been issolated and ignored until the capitulation if the Allies had wanted to, but once again, that is a totally different situation than I was trying to refer to.
One other thing you have to consider, suppose it isn't the local government that you are fighting. Suppose that you are dealing with a Counter Insurgency operation on one of these high pop worlds of the spinward marches. You can't threaten to flatten the whole world just to go after 30K-50K insurgents, it doesn't work. You have to go in and dig them out. If Afganistan and Iraq, taught us nothing else, it has taught us that air power is impressive, and deadly, but you still have to send men in to clean up, take the ground and get the bad guys. (And in a Counter Insurgency, the most important asset isn't an aircraft, or a tank, it is good intelligence, especially HUMINT.)So, if you are going to be fighting, it is probably going to be on the surface of a planet where those types of presures are not going to work on the local government.
Well, I don't see why the Imperium would be getting involved in a counter insurgency situation in the first place. Under the dual soveriegnity system, local governments rule terrestially. The insugency would be against the local government, not the Imperium. The ladder of responses to an insurgency would be:
1) Use local troops.
2) Hire Mercs to beef up the local troops.
3) Ask the subsector, the the Sector duke for his household troops.
4) Ask for Imperial military intervention.
The problem for the local government is that by the time you get to 4, and maybe even 3, you have essentially waived your right of local government. Any local government retains its right to rule because it can effectivly meet its obligations to the Imperium. As long as the local governments pay their taxes and don't violate high law, the Imperium could care less what is going on surface side.
The only time the local government is going to invite the Imperium in is to justify not being able to comply with its minimal obligations to the Imperium, at which point the government would have to really justify staying in power.
I would imagine that if the Imperium did have to intervien, they would be more likely to compell the local government to make some kind of power sharing agreement with the rebels to stabalize the situation than to go out in the woods or mountains and actually fight the rebals. The Imperium could care less who controls the local government as long as the taxes get paid and the trade flows.
(This has all kinds of potential for local intriege, as local nobels might actually foment an insurgency to crash a local government so they could swoop in and claim more of a planets wealth for themselves. This would of course be a violation of the local governments rights under dual sovereignity, and might even technically be treason against the Imperium if the local nobels got caught, but how else are you going to get those high wealth reprentitive democracies to give an outside elite access to the local economy?)
The question then is, who does that fighting? Is it the IM or the IA. If it is the IM, then you are probably going to have two distinctly different TOE; one for Jump units (infantry focused/vehicle light) and the other for Main Force (heavy/mech-armor) units. The majority of the IM will be Main Force units. If it is the IA, then the IM is basically there to gain a lodgement and open up the planet for IA troops to operate. In this case, the IM will probably be more evenly split between Jump and Main Force troops.
If the IA has its own Jump units, then there really is no reason for the IM to have any at all. I would go for that not being that case because I think part of the logic behind organizing the Imperium's military is to break up capabilities and make it hard for any one commander to operate independantly (to protect the throne from ambicious military leaders).
Actually, the 82nd had quite a few more vehicles than any other light division because of their mission profile. They have to be perpared to fight alone for an extended period, so they have an organic, mounted anti-armor company of 5 four vehcile platoons in each battalion.I still see the Imperial Marines as vehicle light, mostly because they are shipboard assets first. Also they are the units tasked with securing the high orbitals, boarding actions, shipboard security, starport security, etc. Given the typical Marine mission you can't use vehicles in many of those missions. At least not full sized armor vehicles.
To take it a step further, does the 82nd (Airborne) or 101st(Air Assault) have a large number of armored vehicles? More importantly do they have many ground vehicles at all?
No, not because, if they had them they wouldn't use them, but because they have limited transport capability. You take the equipment into combat that you can get to the fight. Further for most of their mission parameters the vehicles are either not needed or can't be transported there. So instead they have non-vehicular workarounds where most other units would use vehicles.
The 101st is even heavier because of its organic lift assests. It takes as much space to move the 101st out of theater as a regular mech or armor division.
Well, it is true that the Army became lighter while the Marines became heavier after Vietnam, but a large part of that is mission adaptation. The Army picked up the mission for security in Central America and the Caribbean (which had traditionally been a USMC mission). Conversely, the Marines became more focused on the Middle East and particularly the Gulf. With that mission change the Army needed two force structures, one heavy to fight in Europe, and one light to fight in Central America.The Imperial Marines are the same way. (Again IMTU, YTU may vary.) There is limited transport space, certainly for a typical Fleet Marine unit, because the typical Marine is not on a specialized transport but happens to be on a Cruiser, a Destroyer, a Drednaught, or a Corvette. These ships have a different main role than to take combat forces to a combat zone. Think back a few years to WWII, Marines were on Battleships, matter of fact usually one of the main gun turrets was usually manned by Marines. Speciality vessels were developed for assaulting beaches, but the majority of those were actually developed during WWII. Yes you, today, have ships like the Wasp or Tarawa, where you put a whole batalion+, including equipment on board, but those are relatively recent ships. Until fairly recently, US Marine units were light forces. Matter of fact it was the Marine Divisions that the US Army Light Divisions were based on, so while the Marines were getting heavier and more mechanized the US Army was deploying Light Divisions. Go figure.
Force structures adapt the the missions they are given. The 3I's military has had 500 years to adapt to the post civil war defensive posture of the Imperium. That's plenty of time to develop large assault carries (though my guess is that they had those long before the Civil War period).
Actually, the USMC can be as mechnized as any Army division, they just don't have as many tanks. The Marines in the ground war in Iraq rode into battle on USMC amtracks, the entire division. The difference between the Army and the USMC in this regard is that in the Army TOE the vehicles are organic to the companies, in the USMC the vehicles are not organic to the rifle companies, but have their own seperate command structure.As I recall the only country, until fairly recently, that had mechanized Marine Divisions, was the Soviet Naval Infantry. (And even their Airborne Divisions were Mechanized.)
True, but you do have enough heavy equipment for the division to fight independantly for several days, and more than any other light division (which are designed to fight with external support).You don't have alot of heavy equipment in the 82nd because you don't have the transport craft for it.
You can cut down on that significantly by pre-positioning unit sets of equipment, so that all that needs to be transported are the troops themselves. That was the concept behind the POMCUS sites in Europe and the USMC equipment storage ships in the Persian Gulf.There is a huge difference between lifting the 82nd and the 1st ID. (Not even sure if you could lift the Big Red One by air faster than you could get it deployed by sea, even if it was the only division in the world that you were trying to deploy at the time.)
But even the Type T cruser has space for a Grav APC to move the squad it carries. Also remember that another mission of the IM is to provide security for naval bases. Those forces would probably have enough vehicles to move the entire garrison rapidly to the perimeter or respond to a particular threat if they needed to.Imperial Marines, by the nature of their primary missions and by the nature of their normal mode of transport, are more likely to be light forces. There will be heavier forces, even within the Marines, but they will tend to be lighter overall.
