Surface orders of battle

As a quick scaling exercise, and to further discussion about organization, I’ve updated my hypothetical charts for some tweaked surface formations. Math subject to error and future tweaking.

Basic assumptions:

Scale assumptions are based on standing volume for walkers with no storage-contortions for any vehicle.

Battalion is smallest independent unit, which means that it has some level of organic logistical support (support troops (incl artillery) first assigned at this level).

Generally quadrilateral organization + 1 command vehicle per subunit, except for very large vehicles where command functions can be put into a line vehicle without much disruption to functions, or artillery where HQ element is not on the vehicles themselves.

No provision for specialist sourcebook formations (assault, etc) or for “infantry” only formations – assume all units are AFV equipped for storage purposes. Light units (soft-skinned transport) are trivial volume wise compared to AFV formations. No volume provision for bikes (also not voluminous), but I would assume ratio of 1 bike platoon per battalion troops allocation (scale up accordingly).

Support units are scaled for appropriate vehicles to be supported. i.e. a Scythe unit’s support vehicles are about Scythe-sized. Since these units are not modeled, they are subject to change. Where a vehicle doesn’t make sense for a role (i.e. Broadsword as an artillery unit, assume it’s a scaling placeholder, or a variant).

Basic soft-skinned engineering and logsitical vehicles held at divisional level and above are not designed and not depicted. I assume that many of these functions are landed as containerized cargo rather than in an assault transport.

 

Building-block formations:

Heavy armor
platoon – 3 Scythe + 1
company – 16 + 1 Scythe
battalion – 3 company Scythe, 1 command platoon, 1 company heavy artillery, 1 company battalion troops – 3 platoon TX130 or equivalent (scout), 2 platoons Broadsword equivalent vehicles (support), platoon chariot equivalent vehicles (command and coordination)
Total battalion: 51+4 Scythe + 16 Scythe/5 Broadsword + (15 TX130 + 10 Broadsword + 5 chariot)
= 71 Scythe + 15 Broadsword + 15 TX130 + 10 chariot

Repulsorlift

Total battalion: 68 Broadsword + 17 Broadsword/5 chariot + (15 TX130 + 10 Broadsword + 5 chariot)
= 95 Broadsword + 15 TX130 + 10 chariot

Artillery
platoon – 4 Broadsword equivalent + 1 chariot equivalent
heavy platoon – 3 Scythe equivalent + 1 Broadsword equivalent

1 artillery regiment (4x artillery battalion)
4×71 + 95 = 379 Broadsword
4×24 = 96 Scythe
4×15 + 15 = 75 TX130
4×20 + 10 = 90 chariot

1 heavy battalion HQ/support element
34 Scythe

Total/battlegroup = 343 Scythe, 1468 Broadsword, 474 TX-130, 250 chariot

2x Assault battlegroup/legion:

1 walker infantry regiment (2x AT-AT battalion, 1x AT-SW battalion, 1x light walker battalion)

2×15 + 15 + 51 = 96 AT-ST

1 combat walker regiment (2x AT-SE battalion, 1x AT-SW battalion, 1x light walker battalion)
2×16 = 32 AT-SE
2×3 + 3 + 3 = 12 AT-ACT/AT equivalent

1 Assault walker regiment
12 AT-SP
Total: 1 A6

1 A6 regiment

Total: 4 A6

Total/battlegroup = 12 AT-SP, 18 A6, 36 AT-AT, 24 AT-ACT, 32 AT-SE, 132 AT-SW, 192 AT-ST

Corps troops:

2 SPHA regiment (2 SPHA battalion each, 72 SPHA, 4 A6)

2 airmobile regiment

1 scout regiment (2x light armor battalion, 1x light walker battalion, 1x repulsorlift battalion)

Dropships

1 repulsorlift regiment equivalent vehicles

Engineering elements

 

Usage and drop capacity

My idea is that the ship should be able to drop an assault echelon comprising as much as possible of the surface-contact battlegroups at once to assault a shield generator, allowing for the ship to land or enter atmosphere and release the repulsorlift units as a second echelon/operational maneuver group. Repulsorlift should be able to mass sortie from the bays once in atmosphere/low altitude.

Primary dropship assets are the Chi, potentially up to 20+ units per Consolidator, and Zeta carryalls, probably 100-200 potentially carried in a ship of this volume (they are roughly 2X LAAV/i volume). Infantry dropships are LAAV/i’s – my Imperial era LAAT. Zetas can carry one of any walker below AT-SP size, but can’t lift A6 type craft.

Chi class ships can lift: 2 SPHA/A6, 8 AT-AT/AT-ACT (will probably need special leg folding for ACT, but doable), ~8 AT-SE, ~12 AT-SW, many scout walker (volume terms assuming some compression is like 4x3x2 per AT-AT volume, so almost full assault legion light walkers in 1 lift). A modified Chi without the lift system and ramps could sling an AT-SP in a heavy carryall manner.

An assault loaded ship would probably prioritize enclosed dropships – load a single vehicle in at base, and manipulate the vehicle and its dropship as one volume in the hangar, and don’t open it until it’s deployed. This would be something like a Theta-class AT-AT barge – single walker but most importantly a single SPHA-T. A Titan could probably serve the same purpose for an AT-SP. A Chi carryall would probably better for re-positioning after the initial assault, but by then repulsorlift units would be under the shielding and doing most of the work.

I think a reasonable single lift for the dropship force would be:

1 assault battlegroup drop layout, single lift:

  • 12 AT-SPs in 1 drop (Titan or Chi heavy carryall variant)
  • 4 Chi for AT-ATs
  • 4 Chi for AT-SEs
  • 3 Chi for AT-ACTs
  • 6 Chi for 2x SPHA batteries or full A6 regiment lift
  • 1 Chi for extra A6 (1 for AT-SP support, 1 assault echelon commander in A6 regiment HQ vehicle)
  • 1 Chi for most of AT-ST complement of battlegroup
  • Pre-loading the SPHA force in Theta-sized barges would enable a single sortie of both SPHA regiments to support the assault wave.
  • ~100 Zeta for both AT-SW battalions and for walker mobility after landing, also for deploying and moving containerized logistics and support systems
  • The Chi force will take a large number of scout repulsortanks, chariot type light vehicles, bikes and skimmers in upper bays during each lift

The TIE/sk’s from Rogue One ended up being atmosphere-only platforms (which is a convenient explanation for why they didn’t show up in any of the space battles in the OT). Would they be the equivalent of attack helos like the Apache / Havoc?

What’s your take on WEG’s statement that the Evakmar-KDY was designed to carry more than a full corps, in anticipation of plans to expand unit sizes in the Imperial Army? Is there any extra room on the Consolidator to reflect this, or is it packed as tight as it can get?

Chris Bradshaw

Well it depends on the corps in question. A lighter, repulsorlift formation for garrison work is going to take up a lot less room than the breakthrough walker formation with all the AT-SPs diagrammed above.

Light Walker platoon – 3 AT-ST or -DP +1 company – 16 + 1 battalion – 3 company, 1 command platoon, 3 AT-ACT + 15 AT-SW support element Total battalion: (52 AT-ST) + 15 AT-SW + 3 AT-ACT 3×17 + 4 = 52??? Or is the “+ 1” of the company part of the command platoon? And you forget to add the extra 15 AT-SWs in the Light Walker battalion to the Combat Walker regiment. So there are even more Zeta? Zeta’s? Zetari? needed to droo the AT-SWs in a single drop. Or maybe in a Chi with some space… Read more »

On the updated image, it looks like the Scythe artillery variants are the wrong color; the size is right, but the color is the same as the Broadsword

A couple thoughts on specialist formations from the sourcebook… Assault Battalions & Regiments could, with some minor tweaks, be used to make AT-AT formations, with AT-ATs in the “Heavy Tanks” slots providing transport to the unit’s infantry. The description at both the Battalion and Regimental level describes them as being used for direct assault on enemy strongholds, as well as being the vanguard for combat landings. The organization of Bike Scout units at the Platoon level is pretty screwed up, with two 5-scout lances on bikes and 2 line squads of troops with no listed transportation of any kind.

It bugs me the picture only shows 24 scythes for the artillery battalion. Or the broadsword equivalents in another blue. Or the picture showing 5 AT-ACTs for a battalion.

24 Scythes to an Artillery Battalion works out to 8 Scythes in 3 eight-gun batteries, which is consistent with real-world artillery units.

Yes. 3*8 works well but I mean the picture is not consistent with his OOB: Artillery platoon – 4 Broadsword equivalent + 1 chariot equivalent heavy platoon – 4 Scythe equivalent + 1 Broadsword equivalent company – (16 + 1) Broadsword + (4 + 1) chariot equivalent heavy company – 16 Scythe + 4 + 1 Broadsword equivalent battalion – 2 company, 2 heavy company, Broadsword company (support), 1 company battalion troops Total battalion: (34 Broadsword/10 chariot) + (32 Scythe/10 Broadsword) + (17 Broadsword/5 chariot) + (15 TX130 + 10 Broadsword + 5 chariot) = 34 Scythe + 71 Broadsword… Read more »

Real world artillery units are just as often organized into six gun batteries, and 4 batteries of 6 guns, of 3 sections of 2 guns is a more flexible orginization than three large batteries. Heavy artillery batteries are typically deployed independently, not as a massed battalion. In example, 6/32 FA in 1967-1968 was deployed near the DMZ in such a fashion as to be able to literally bisect the country with overlapping fields of fire, the 175mm and 8″ howitzers having a 20+ mile range. A bigger battery Organization wouldn’t have done the job, and those batteries were 2 section… Read more »

As far as lift capacity, I think both the Army Corps and the Consolidator should have their own landing craft that combine to perform a full-scale drop. A Consolidator isn’t going to need to stick around in orbit supporting an Army campaign that goes on for months or years; other craft – such as Modular Taskforce Cruiser variants – can perform much of the support and logistics functions. Off-hand, I’d say that the majority of the heavy lift capacity (Titans and Chi’s) would be attached as part of the Consolidator’s air wing, while the corp’s aviation detachment would be primarily… Read more »

Regarding the Scythe, how are the different variants organized. I assume the mass driver and MLRS variants are artillery, and the gatling blaster is air defense, with the twin LTL as the main battle tank, but where would the ion cannon fit?

Also, on a related note, there’s a pattern since the prequels of tanks in the SWU having a mixed energy and projectile armament. Have you considered a Scythe with a single LTL paired with a high-velocity projectile launcher, ala the one on the -SE or the -TE?

The AT-ST’s inclusion in combined arms walker units irks me just a little. Mostly, I focus on the unsealed interior (the viewports) making it more vulnerable to gas attacks or area effect weapons like flamethrowers, especially in combination with the AT-ST’s mission as a “scout.” Based on the performance at Endor, the AT-ST seems more like a mobile infantry support platform, working best when infantry units can help protect it from boobytraps and ambushes. The AT-DP has advantages in this regard, but suffers a relative lack of versatility in its weapons loadout compared to the AT-ST. And yes, they were… Read more »

For units like the AT-AT or -A6 companies, are you picturing troops being permanently assigned, in the same manner as a Mechanized Infantry squad? I could see serious flexibility issues in permanently tying a large group of troops to one vehicle type. IMO, it’s more flexible to just have, say, an infantry battalion or regiment which can be attached to a company or battalion of heavy combat transports for either a single assault or a full campaign. The US Marines take this approach; you can take a company of Marines and deploy them by helicopter (air mobile), amphibious tractor (combined… Read more »

What are your thoughts on organic air defense units? I know you’ve got the anti-air variant of the Scythe, and an anti-air Broadsword would be an easy mod. Does the AT-AA work for the walker units, or are you picturing something else?

Another idea from Renegade Legion: there is still room for infantry units (or at least primarily infantry) as Garrison troops. In fact, static garrisons probably make up the bulk of the Imperial Army’s strength, just with an emphasis on holding ground already taken as opposed to fighting on the advance and securing new ground.

It’s also likely that there will still be some true Light Infantry units formed in response to the Alliance, especially for use in close terrain that isn’t conducive to vehicle combat.

For logistics, I see the Zetas being hugely useful, not just for flying in heavy vehicles, but for flying in standardized containers loaded with supplies, either to central depots or (seeing as how it’s armed and relatively well protected) closer to the forward lines. The LAAT/c from AOTC could, in addition to flying in AT-TEs, be used to deploy “portable power generators and shield projectors, observation posts, field medical centers, supplies and fixed artillery,” (Star Wars Complete Locations, page 88); the Zetas should be able to do all that and more.

Ryadra777

Interesting and very well thought out. But there are 2 things I want to point out.
1. Does the yellow-green block represent the TX-130? and if so why doesn’t have the name tag did you forget to give it one?
2. How would the AT-ACT be useful in battle? Since it’s role was to carry cargo which is in it’s name ‘All Terrain Armoured Cargo Transport’.

Engineering Vehicles: Renegade Legion has some great ideas for sci-fi combat engineering vehicles. CEV’s in that universe come equipped with multiple Engineering Attachments, including: 1). Planar Laser – effectively a horizontal energy saw used to clear out trees or rock formations to create a clear path for ground-level repulsorlifts. 2). Minesweeping Field – projects a wide-angle gravity field ahead of the vehicle to detonate mines. 3). Digging Cannon – fires delay-fused explosive shells into the ground that create large craters, big enough for vehicles to use as hull-down positions (most vehicles have them, but engineering vehicles have 2-3 times the… Read more »

While it isn’t described as such (and I’m not sure he ever actually said what it was), I always assumed the large circular plate on the front of the Broadsword was a tactical tractor beam projector for anti-mine work and light digging/entrenching. Such a thing is pretty important for actual armor going back to WW2.
