Polish Civil Defence, Air Raid Shelters and Disaster Relief.

The Cold War Polish people lived in a militarised society. They prepared for a conventional war on their territory, and in the T2K world this preparation will bear fruit.

It has to be remembered that in the People's Republic of Poland everyone had a job to do and if war erupted everyone had a job to do in that. Civilian training in disaster relief was on a level unequalled in the West. The civilians had shelters and were expected to use them. In devastated areas civilians were expect to fall back with the troops and not stay in place. Civilians will be active in the defence of their country and NATO is an invader.

Civilians were incorporated into the war effort under the umbrella of the Obrona Cywilna PRL (OP).
The OP was the primary civil defence organisation and a large proportion of the civilian population had a role in it. The OP as a civil defence unit is off limits to hostile forces and it is illegal to utilise their equipment. Civilian infrastructure such as school buses and bus shelters were designed to be quickly converted into ambulances and aid stations. This thinking permeated the Polish government and society. Firemen, police and medical staff all wore military uniforms. In fact nearly everyone in this situation wore uniforms, it would be rare to see civilian clothes after a while. Civilians had access to shelters and these were stocked with food, medicine and NBC equipment. Huge amounts of earthmoving gear was available to them to shift rubble and enter damaged buildings. The OP had comprehensive NBC detection and decontamination equipment that included decontaminating every facet of life right down to livestock.

Now, it's very hard for me to tell as I don't speak Polish but there was another organisation that has the acronym ZOS. They were either part of the OP, ran in parallel to them or were superseded by them. ZOS had fire, medical, sanitary, technical, social and specialist shelter staff all organised along military lines. ZOS seems to have worked alongside the MO (police) in rear area operations and go into action to mitigate the effects of the war on the population. Poland had the experience of the Nazi occupation to draw from and had no illusions as to how bad war could be and prepared accordingly.

Air Raid Shelters were short term shelters. They were located in a huge amount of places such as railway stations, hospitals, industrial plants and government buildings. These things were not small. They usually had double thick steel doors, a decontamination room, a generator/air filtration/water systems complex, medical centre, storage area for uniforms, helmets, medical equipment, tools, food, and other stores, a series of actual shelter areas, a commander's room and an array of escape tunnels. Most were buried well below ground with a concrete shield overhead and would have survived anything but a direct hit from a heavy bomb. In the twilight 2000 world these will form the nucleus of survivor enclaves. During the real world many of these shelters existed in structure only but during the drumbeat to war it is unlikely that Poland would have neglected these structures.

Note that Nowa Huta near Kraków had over 250 of these structures.

On my quest to make the perfect Twilight 2000 Sheridan I think I've finally found it.

Believe it or not but way back in 1967 there was already concerns that the M81 (as it was then) Gun/Launcher may not be a good idea. As such Rock Island Arsenal did a crash program of four other weapon systems to fit in the M551 turret should the M81 develop problems.

Of the four only two were recommended mainly due to space problems, although it was mentioned that if serious redesign work was done all four would fit in the turret. The two weapon systems were:

- M32 76mm Cannon, the same as was on the M41 Walker Bulldog
- XM180 105mm Gun/Howitzer from the XM104 super mobile lightweight howitzer (which really should have gone into service)

Of the two the XM180 was the preferred weapon system as it coupled low pressure and trunnion loading with high damage output and ammunition that was still largely in service.
This weapon fired much faster than the existing M81 because it didn't need a compressed air purge to blow out the bore so the combustible cartridge cases wouldn't ignite prematurely. It's likely that by the time of the Twilight War an A1 version of the gun/howitzer would have been developed with a bore evacuator for even faster firing. Notably the XM108 could fire any 105mm howitzer ammunition in US stocks and new racks for the vehicle gave a stowage of 50 Rounds. (I note the UK ammo has a squash head round)

If the M551A1 is the M81-armed standard version with vision upgrades and a minor modernisation package that would make the M32 76mm the M551A2A1 and the XM108 105mm the M551A3A1

Here's an image of the gun way back in 1967

The Polish PT-91 Twardy MBT really should exist in the game, it's awesome.
Although prior to the dissolution there was a strong drive to keep military equipment the same across the board, invariably Russian equipment, it's obvious in hindsight this was impossible to maintain. I guess to ease the problems that might arise from this situation there'd be lots of cross-training with Russian kit so when they resupplied other national armies with gear in case of loss of industrial capacity due to strikes or being overrun there were fewer problems.
Of special interest is the PT-91EU which was an Urban Warfare variant. Although in real life this vehicle turns up way later in 2011 the exigencies of war would see it being developed far earlier. Due to its high survivability it's likely more of these would survive than the other variants.

ZSU-23-4M2 "Afghan" version.

What, it gets worse?!

The deadly "Zoo" or "Shilka" evolved over its ongoing lifetime and the ZSU-23-4 in the books is not necessarily the ones your PCs will meet on the battlefield.

During the Soviet-Afghan War of 1979-1989 the Soviets developed the M2 kit for their Shilkas. This was the following and converted the weapon from the anti-air role to the ground support role:

- Removed the Gun Dish J Band anti-air radar
- Installed enlarged ammunition bays doubling ammunition capacity from 2,000 to 4,000 rounds.
- Installed the TPNZ-49 tank night scope.
- Installed the PSNR-5 man-portable ground surveillance radar.
- Ammunition was a mixed belt of BZT API and OBZT HE-T ammunition to destroy by blast and penetration.


Now, it's important to note that these modification kits exist in the Twilight 2000 era. It just a job of dropping the beast back to a workshop and having them fitted. It's likely this will happen wholesale when the air threat diminishes.

However, what you can use against Afghan rebels and what you can use against NATO regulars are not the same thing. NATO troops can reach out and kill things at night time and the Shilka can only accurately hit targets at around 1,500m in the ground support role. It's going to need some sort of mix of Applique armour, ERA and bar armour.

I can't tell if the Shilkas in the book had the old, unmodified engine that was slow in the book and all the upgrades the vehicles had by the Twilight 2000 era M3 vehicle.

I do love vehicles that, to put it bluntly, were no good.

If it was that they lost their raison d'être due to technological advances, if they were good ideas that were ahead of their time or in case of the vehicle coming up, they were simply a crap boondoggle, I do love my failures.
The M247 Sergeant York SPAAG could have been awesome. It's one of those vehicles that simply "looks right". It was an utter failure, but the failure was mainly due to its design criteria as much as dodgy corporate swindling and corruption.

What the US Army wanted: A ZSU-23-4 with bigger guns and a fast engine.
What the US Army asked for: an SPAAG using two heavy guns and a heavy radar on an out of date chassis that still had to keep up with the M1 Abrams, one of the world's fastest tanks.

They specified the M48A5 chassis because they had lots and they were very reliable. They also stated that it had to use off-the-shelf equipment so the radar was a repurposed air-to-air radar, not even a ground attack radar. Now, Ford Aerospace seemed to have been thinking if they got the contract the could simply deal with the issues later. Issues like making it work.
Really, the whole sorry tale is too long to go into here. I do recommend you look it up now that 35 years have passed.

What I want to do is suggest that the M247 didn't ignominiously end its days being blown to pieces on live-fire ranges but that the 50 that were made in our alternate universe languished in a boneyard simply because everyone was too embarrassed to talk about them. There they sat, essentially useless and incapable of even defending themselves until the final phase of resupply for the European campaign. By this time the Mil-24 Hinds were all gone and the USA is desperate to send its troops ground fighting vehicles. They looked at the M247s sitting there and gave them the ZSU-23-4M2 "Afghan" treatment.

The hypothetical M247A2 is purely a ground support vehicle. It has had its radar stripped out and the AN/PPS-15A(V)1 ground search radar (1,500m for personnel, 3,000m for vehicles) placed in the forward radar nacelle.
The ammunition is increased from 580 to 650 rounds.
The turret armour is given applique panels that bring it up from STANAG 4569 level 3 to level 4 armour protection, capable of resisting the KPV 14.5mm. A sliding mantlet is provided to protect the crew from direct fire of the same level. The rear of the turret is kept the same and the hull is of course the basic robust M48A5. In the European theatre ERA blocks and wire/bar armour were occasionally used by some units. This extra armour drops the road speed to a slow 40kmh, a speed demon it is not.
The turret had a large bustle rack at the rear and is still roomy after the removal of the large radar even when the extra ammunition is fitted.

The commander's cupola from the LAV-25 was fitted and has a NATO heavy mount capable of accepting the M240E1 GPMG (spade grip version), the M2HB HMG or the Mk19 AGL. Many were equipped with gunshields at various times.

The sights are upgraded. The optical sights are retained and light intensification added. The commander has no override for the gun. At least one of these vehicles was fitted with thermal sights during its war service.
Note that the 40mm twin autocannon are belt-fed, a huge improvement over the crew-intensive five round clips normally used. Its crew remains three with commander, gunner and driver, making it something of a bear for maintenance and an endurance test when keeping watch.
