Hi!
As I analyze the inventory data here are RAW numbers. Note that these are the numbers of what the FINAL list will contain. What I have set aside or will at one point be "cast off" has not yet been quantified. That's a whole other inventory...

Imperial Guard
375 infantry tactical stands
105 heavy weapons stands
90 Assasult IG stands
Over 100 HQ stands
25 commissar stands not including those incorporated to command and platoon leaders
20 ratling stands
30 ogryn stands
10 psyker stands
150 rough riders with command
60 bikes with command
45 IG landspeeders
40 Sentinels
24 rapier guns and crew
24 static artillery guns
15 static Basilisk style guns
24 static rocket (manticore) batteries
18 static AA guns
142 chimeras
over 50 command chimeras
40 chimera variants (all types)
60 whirlwinds
107 Manticore rocket artillery
60 Bombards
124 Basilisks artillery
6 Earthshaker guns with carriage
45 griffon cannons
30 Medusa heavy mortars
33 Salamander tracked vehicles
143 Leman Russ tanks (all types)
36 vanquishers
39 executioners
63 conquerors
42 Thunderer siege tanks
39 tank destroyers
27 stormhammers
23 shadowswords
24 stormblades
6 baneblades
30 FW stormblades
33 FW stormswords
21 FW baenblades
32 predators (all types)
12 hellhounds
32 vindicators (all types)
36 ragnarok tanks
30 thunderbolts
30 marauders
19 FW marauders
15 Valkyries
18 Vultures
18 Lightning strike fighters
12 custodian knights
12 castellan knights
18 errant knights
3 errant barons
20 lancer knights
5 lancer barons
21 paladin knights
4 paladin barons
12 old school knights
28 Gorgon assault vehicles
7 Hellbores
6 Capitol Imperialis
3 Leviathans
15 ordinati (all types)
Total points (net epic values): approximately 140,000 points.
This calculation is only for FULL companies. If I would added the horde of support cards that don't add up to a full company it would be at least another 20k for around 160k.
It does NOT include knights or titans, which I list together under a mechanicum list.
This is the largest army I own and will not be adding anything to it beyond what has not been painted or queued to be included.
I have no clue on the value of this army by itself. It would take someone more intrepid than I to pull that off.
