Type: Mixed Agri-Civilised World
Population: 30,000,000,000
That is not an agri-world. It's not even vaguely an agri-world.
The Imperium couldn't give a monkey's what you grow if you don't export it - and if you have a population between 4 and 5 times that of contemporary Earth (which struggles) then either you're going to be growing food to feed your own population or the entire planetary surface is dedicated to soylens, kelp or similar low-grade high intensity agriculture and you've basically obliterated any level of natural ecosystem. Agri-world means major food exports on top of feeding the world's own population (which is normally small)
Food Supplies, Monetary, Military, Oil
Food supplies addressed above.
Monetary - so so. Money is, after all, merely a device to simplify trade. There has to be something physical to back it up, especially across interstellar distances.
Oil - read Promethium, the generic imperial term for 'fuel liquids' (which actually includes more than just what we think of as oil, such as synthetics, flammable silicon oils and methane ice).
Military, fair enough. A nice block of troops are always welcome, especially out on the edges of Imperial space.
Tiananmen imports many things from the rest of the Imperium.
Such as? Most civilized worlds are largely self-sufficient, niether importing or exporting anything except the tithe. You get worlds dependant on major imports when they have an 'unbalanced' economy - normally because their economy is centred around one element (like a genuine agriworld, or mining world, or...you get the idea)
Essentially, either say it's a borderline hive world and give up on growing food or massively scale back the population and claims of industry (which may be important to the planet but is irrelevant on a sector scale)
Considerable Space Fleet and Orbital Defences
You've already scrubbed the space fleet. 'Considerble' orbital defences is still rather a claim. As with an agri-world, you have to be rather special to be able to claim 'considerable' - which on an Imperial scale means you're approaching a fortress world (like Cadia, Nemesis Tessera, Vraks, etc, etc.). Any civilised world will have a decent belt of defence platforms and anti-orbital guns. But 'lots' stands out. To give you some numbers to plug in, an old bit of fluff from the 1st edition of 40k stated that 'standard' defences for a world was 1 ground based orbital defence (each one being about ten defence lasers or torp silos) battery per thousand kilometres of plantary radius - so contemporary earth, for instance, would rate about sixty defence lasers - plus maybe another dozen or so protecting specific installations (e.g. governor's palace, PDF hq, planetary capital city).
These defences are likely to be lower in Tiananmen's case as they've recently been blown to bits - the Imperial Fleet having to fight its way through them as well as the Air Caste fleet.
a well trained and extremely large PDF numbering 12,000 Divisions
Extremely large.
Taking into account the description later, each division consists of
Red Guards: 20,000 infantry
Mechanised Red Guards: 15,000 mechanised infantry plus 3,600 chimera crew (2 per vehicle) - total 18,600
Battlemasters: 10,000 leman russ crew (between 4 and 6 per tank depending on sponson fit), 4,000 chimera crew, 3,000 artilllery vehicle crew (about 3 per basilisk/griffon/manticore depending on type), and 4,000 scout vehicle crew (2 per salamander) - total 21,000
That's a grand total of 59,600 red guards per combined-arms division, not counting logistics corps, adeptus mechanicus and adeptus ministorum, commissariat, drill sergeants, general staff and other rear-echeloners.
Given that there are 12,000 divisions in the PDF, and a further 8,000 divisions serving off-world (or an equivalent number of regimental formations - expect them to get broken up over time as the guard forms and re-forms to re-organise around casualties) that's 20,000 divisions, or 1,192,000,000 front line troops under arms.
That's one in thirty of the population, or about 4% spends his days getting shot at. The actual figure would be much, much higher - the Imperial Guard has a pretty big divisional wedge, especially in an army that's 2/3 mech or armoured.
For comparison, modern China (for instance) has about 3 million standing troops in a billion, or less than a tenth of that (0.3%). Even if you add in the million or so reservists and 15 million militia (who are not going to be lavishly equipped mechanised/armoured formations) you only get a grand total of 18.8 million, or about 1.5%.
4% militarisation is equivalent to North Korea - a country so heavily militarised that any semblence of an economy is basically dependant on foreign material support.
To put it another way, half the number of Red Guard -
at least (I'd say reduce by three or even four is more likely) - if you want a thriving economic world as well as just a fortress. If reigning in the population, cut troops appropriately as well.
Tiananmen is a beautiful world. Tiananmen has four largest Archipelagos, the biggest of which is located in the middle of the planet. The other three archipelagos are located West, North-East and South-East of the world. There are no deserts or arid areas on Tiananmen, the north and the middle regions of Tiananmen are temperate while the southern regions are tropical. There are many mountain ranges in the north and some in the middle and southern regions. The northern regions enjoy beautiful winters.
No uninhabitable regions at all? Unusual, but - I suppose - possible.
Bear in mind that the 'south' will match the 'north' - unless it's only south with respect to a 'central' continent, not equally far south of the equator.
Note that unless you mean 'continent' rather than 'archipelago' you're not using much of the planetary surface, so 30 billion people goes well out of the window unless you want underwater hive cities.
The Economy of Tiananmen is stable, strong and is at a very tall height.
Last phrase unneccesary and non-sensical - if it's stable and strong, that's all you need to say.
Food Production is extremely high and ever rising
So it's not 'stable' then. Stable means virtually no change, good or bad.
Tiananmen has a reputation of being a low-cost manufacturer
Producing what? Bear in mind that something has to be extremely valuable (to someone) to justify the cost of interstellar shipping. And again, you have to be producing a shedload of stuff to meet the needs of half a billion troops (assuming the Departmento Munitorium takes care of the Guard Regiments) and 29 billion other people
and exporting things. It's not possible to do this and be an agri-world at the same time.
Tiananmen has large Oil Reserves, thus there is much oil rigging in the tropical parts of Tiananmen.
That's fair enough - promethium is valuable enough to the Imperium that it'll go after it wherever it crops up, so if it's availible in quantity on an inhabable, populated world they'll turn the appropriate region into a geological pincushion to extract it. Once again, you're talking about supporting half a billion troops, 29 billion other people,
and the planet's industry
and exporting the stuff. That's a
lot of oil rigs (and supporting industry) and basically eliminates a lot of the tropical region for food production or living space.....
The Education of Tiananmen is great. There are a great many numbers of Primary Schools, Secondary Schools, Universities and Colleges, these Schools and education facilities follow a public education program.
Fair enough, if it's a rich world. Socialist nations tend to have very good base-level education, because it's one of the problems that's easist to attack.
About 99.7% of Tiananmen's total population is Literate
As noted, unlikely. If you're looking at an industrial hive world, or a subsector capital, then 95% is possible. The 70% you've suggested sounds about right if the industry is centred around agriculture and manual labour-heavy tasks.
99.8% of Tiananmen's child and teenaged population is currently in schools and universities.
Uhh, the workers are working on the land.
School education, maybe. Nowhere near 99.8% would go on to university - as noted, you wouldn't get university graduates (given the cost of such) working in a field or as a low-grade scrubber on a promethium rig. Or for that matter as a Red Guard squaddie. If the economy is stable the provision of higher education will have evolved to match the demand.
Evilmonkey's point was that you're not noting what percentage of school leavers get higher education (which is pretty limited by comparison).
The Culture of Tiananmen is old and enormous and stretches back even before the Imperium of Man
No, it doesn't (well, maybe a hundred years or so):
Tiananmen was colonised during the Great Crusade
more modernised than other Traditional Chinese Cultures, though the Tiananmen Culture now does preserve the Traditional Chinese Culture.
'Elements of' probably needs adding in here. It can't be a completely traditional Chinese Culture because its a heavily industrialised world.
The Tiananmenren do not sing players and hyms of the Emperor
Well - some sort of classical spiritual activity is to be expected, even if it's just preachers exhorting the masses to follow the teachings of the various Saints of the Imperium.
Otherwise a ship turns up with =][= on its side and the planet goes whumpfff...
they have the Emperor's quotes
Where did they get them from? I should point out that virtually no-one in the Imperium actually has a record of anything
actually said by the Emperor, any more than they have an
actual image (rather than 'best guess' devotional artwork). I know that you're trying for Mao's 'little red book' but a book of prayers/inspirational sayings is possible, just not quotes from the Emperor himself.
it was a beautiful world to the Imperium and they ordered a colonisation process on Tiananmen.
Beautiful is probably the wrong word. The Imperium couldn't care less about a world's beauty - either it was valuable (in which case it's often over-exploited to the point of environmental breakdown) or not.
During the Horus Heresy, Tiananmen provided food supplies to those armies Loyal to the Emperor.
And troops. Everywhere had troops demanded of them.
If it's on the far side of the galaxy, it probably didn't achieve that much - as with Calgar's crusade forces, it would be so long before they got back to the main battlefronts that everything was by and large decided. Their troops (as with the ultramarines and fists) might well have played a part in the scouring, though.
The Age of Apostasy had a horrible effect on Tiananmen.
Not unlike everywhere else, then.
Vandire seized possessions and food from the people of Tiananmen and raised their taxes with no apparent reason.
Vandire himself certainly didn't. He's on the other side of the galaxy on Terra and - being High Lord - couldn't care less about the fate of one planet. The planetary governor, or lord-governor subsector, or Sector government might.
But the 1st Tiananmen Regiment was founded shortly before the Age of Apostasy, thus the Tiananmenren fought against Vandire.
1 regiment? That's one Imperial guard regiment in the midst of the second biggest war the Imperium has ever seen. Doesn't register.
They might have fought some (locally) famous actions, but they most certainly weren't involved in any of the main events because they happened so damned far away.
Although the Tiananmenren supported Sebastian Thor, Vandire never got round to declaring exterminatus on Tiananmen, as he was after Sebastian himself.
Again, Vandire probably wouldn't have even been bothered about matters concerning one world - his minions had far more important things to tell him about. He basically issued a general order of 'burn anyone who opposes me'. Those elements of the navy loyal to him either refused to carry out the action or never got the chance (more than possible) - or else there were no Vandire loyalists in the region - but then they would probably never have got involved in the war in the first place as there's no-one to have been oppressing them.
Tiananmen supported the Damocles Gulf Crusade and many Tiananmen Regiments joined the Crusade.
You make it sound as if there was a choice. The Departmento Munitorium announces that there is a crusade being mounted, and tells you that one quarter of the Red Guard divisions are being shanghied for distant worlds and exciting opportunities to get killed. You can like it, or you can be burned as traitors. Your choice.
After the Crusade was over, Tiananmen was getting more concerned with the Tyranid threat.
Again, wording could use a bit of work - the re-emenrgence of the 'nids is the
reason the crusade was called off.
Revisionist Chen
This title appears with no particular reason. What is it that he is supposedly rewriting?
the only problem facing Tiananmen now
Aside from an encroaching hive fleet and the possibility that the tau might try to annexe Tiananmen again - with the Fire caste landing in force this time rather than using a stooge governor as a cat's-paw....
These remnants of Tau have kroot on their side but no vespids
As a point to note - many tau cadres include auxillia forces, but if being deployed as a force to back up a seceding Imperial governor, you're trying to make a best impression. If you want to convince the world's population that the Tau Empire is really cute and cuddly, then if it was me I'd say introducing them to the aggressive, cannibalistic kroot is probably a bad idea. On the other hand, if you want a likely culprit for 'atrocities' beyond the tau going mildly loony in the wake of the Aun being killed, kroot are a good candidate.
These Tau have no vehicles and are not capable of creating vehicles, but they are capable of creating their own small arms.
Tau small arms? Them's some pretty high-tech hardware for guys in caves in the mountains. If they (and the surviving Chen-ists) are using human hardware, maybe. But not tau hardware.
these Tau create insurgency on Tiananmen, but this is contained and Tau insurgency is considered to be only incompetent terrorism.
The tau are many things, but are rarely incompetent. Small-scale, maybe - but not incompetent. It's also likely that the Tau Empire would try and support this as best it could - especially since there are its own people still stuck on the ground.
The Tiananmen Regiments fought against the Tyranids, they were less successful than they were in the Damocles Gulf Crusade and the Age of Apostasy, but they did win many victories regardless. After the 1st Tyrannic War, the Tiananmen Regiments were sent to war zones again.
Point of history: The first tyrannic war ran from the destruction of Tyran to the assault on Macragge. It predates the Damocles crusade by several centuries. The Crusade was called off after the appearance of
another hive fleet, beginning a second tyrannic war which is still going on.
Point of background - being anything less than sucessful against the tyranid swarm generally means extermination.
