Default Vehicle flamethrowers

I had a look at vehicle flamethrowers and it was quite interesting. First thing I would say is that I would remove the Flame weapons ability to block LOS so high burst rates don't present a problem.
The game has two generic flamethrowers;
Wpn 83 representing a normal manpack firing about 1-2 litres per second out to less than 50m and with a HEKill of 25.
Wpn 108 the purpose built vehicle flamethrower firing a maximum of about 26 litres per second out to 100m and has a HEKill of 40.
But actually most vehicle flamethrowers performance are closer to the manpack than the vehicle weapon 108 but get the vehicle weapons hitting power and range. The number of bursts allocated often doesn't reflect the vehicle capabilities either.
For example
Crocodile fires flame at 26 litres/second out to 80m while Sherman E4-5 fires 3 litres a second out to 55m, but both vehicles get wpn 108 HEKill 40 and range 2.

So to get a more accurate range of flamethrowers in game we need to know the various flameguns flow rates, flame fuel tank capacities and ranges. Many are available here on page 104.
From that reference, with a few gaps filled in from elsewhere,

As you can see there is a full range of different vehicle HEKill values and ranges.
Different flow rates for a particular weapon correspond to different nozzle sizes larger nozzles give higher flows and longer ranges.

Using the Gun tables HEKill values we can make the following changes to Flame weapons.
UK Keep 108 as is. Create wpns Gun No. 14. and 20.
Canada Keep 108 as is.
Aus/NZ Change 108 HEKill to 50 as Gun No. 21.
India Change 108 HEKill to 30 as Gun No. 5, Range can be 1 or 2.
USA Keep 108 as is. Create wpns Gun No. 2. 10. 16. and 17.
USMC Recycle 108 into Gun No. 10. Create wpns Gun No. 2. and 6.
Russia Change 108 HEKill to 31 for Gun No. 24/25. Create wpn Gun No. 22. and 23.
Germany Change 108 HEKill to 29 Range to 1.
Italy Change 108 HEKill to ~29 Range to 1.
Japan 108 Not required
Spain Change 108 Range to 1 HEKill is debatable, it is a large WWI German flamethrower.

Crocodile has 80 real bursts, in game it has 32, thats a decrease by a factor of 2.5 Ive applied this factor to all the following calculations for number of bursts. So I've divided fuel tank capacity by lts expended per second and then again by 2.5.

HEKill is where the discharge rate falls on a line between 25 For manpack and 40 for churchill.
Repeat entries are for Flamethrowers with different flow rates according to which nozzle is installed.
For manpack flamethrowers installed into vehicles I have used 1lts/sec flow rate. Except for soviet units 592/594-6 and 010 ND Italian units 346 and 61 where I used 2lt/sec
Adjusted Number of Bursts can be halved by assuming two shots fired in the turn and increasing HEKill.

Some Errors etc in the OOBs

Unit 560 Wasp MkI never saw service, picture is of Ronson Ronson Carrier never saw service. Here is a picture of what Wasp Mk I looks like.
The 818 Ronsons shipped to Europe(England) by Jul 43 stayed in England (they had been deemed unsuitable for service and only used for training) to be later converted to MkII or MKIIC.
In his book book British battle tanks Fletcher says "1000 wasp mkI used only for training" He goes on to point out that Wasp IIs, Unit 128 (picture is of Ronson) first action was in 7/44 game has it available 5/44. Wasp Mk II doesn't have a MG as only two crew, so remove MG (Flamethrower is in bren slot). By the end of the war UK had adopted the Canadian wasp IIC layout (341 lt tank) with 3 crew.
Unit 991 Comet Crocodile only ever existed as an incomplete prototype and saw no service. See
Unit 561 Churchill Oke, An experimental vehicle only used at the Dieppe raid, 3 made, 3 destroyed at Dieppe so service dates should be from 8/42-8/42 rather than games 8/42- 12/43.
Unit 318 LVT-4(F) not used before VJ day so start service date might be 9/45 instead of games 3/45.

Unit 128 Wasp Mk IIC picture is ronson which never saw service. IIC first available Aug44, game has Jun44.

Unit 036 Matilda Frog. British and American tanks of ww2 by chamberlain gives introduction date of late 44, game has 1/43 more than a year earlier.
This site
Gives 1945 as the start service date. It also mentions that the vehicle went into action with just 112 gallons of fuel, because the jettisonable 100 gallon fuel tank wasn't filled, Fletchers book mentions that this fuel tank is vulnerable.
According to Fletcher frog could carry in total 1100 lts, however he says this
"it seems that the front and side reserve tanks were never filled when the frogs went into action." which drops the total to 818 lts. The "Frog" mostly went into action with 509 lt of fuel. Used mandatory 45.46 lt bursts, 20 sec delay between shots.

Unit 314 M4 E4-5 Flame is probably meant to be M4 with M3-4-3.
Unit 312 M42B3 Game vehicle has no CMG and crew of 5, Hunnicutt gives CMG and crew of 4.
Unit 811 T33 Game has start date of 1/46, BMG and 5 crew. Hunnicutt has first pilot delivered on jan 48, shows bmg removed and 4 crew, vehicle also has a second turret top flamegun with 50yds range that doesn't appear in the game. Vehicle development occurred over a long time, so actual dates of various removals and additions is unknown to me.
Unit 318 E7-7(PTO) See
Crew is apparently 3 not 4 as in game.
US unit 11 is same as USMC unit 205. US unit 314 is USMC unit 208. US Army didn't get these vehicles until after the Marianas operation so start date in US OOB should be after Nov 44 for both units, game has 6 and 11 of 44.

According to Hunnicutts book Sherman a history of the American medium tank.
Unit 205 M4 E4-5 Flame introduction date is July rather than June 44.
Unit 208 M4 E4-5 Flame is probably meant to be M4 with M3-4-3.
Looking at this footage
and given the weapon is a "modified" ronson I would give the POA-CWS-H1-5 series range of 1.

According to
Unit 593 OT-27 carrys a manpack flamethrower, game has Vehicle flamethrower.
Unit 592 OT-26 MG is BMG not CMG. ie Turret ball mount.
Unit 594 OT-130 Production began in 1936 game has 35. MG is Turret mounted BMG not CMG.
Unit 010 OT-133 is Finland Unit 237
From Tanks of the ussr by Ludeke
From tank encyclopedia
"however, the last HT-26 tanks were used in 1942. The surviving HT-130 and 133 tanks were deployed in the Leningrad Military District and were used in the defense of Leningrad between 1941 and 1944." Game has much earlier end service dates.
Ludeke gives 45mm Ammo for KV-8 as 92, game has 116, KV-8s should also probably have 92, flame paraphenalia replaced some shell storage.

Unit 106 Flammpanzer II
The book Nuts and bolts PZ.Kpfw. II Auf D/E and variants provides these details
Turret had 30mm all round game has 2 for sides and rear.
Turret MG ball mounted so might be BMG instead of TMG.
Flamingo came equipped with smoke candles. Doesn't have them in game.
Unit 588 FwPzKw B2 740(f) There are 3 versions one with 160 lts, one with 500 litres and the production version with an very large external tank looking to be about prob 700lts. CharB production date supposed to be nov 41 game has 6/41 but that could be one of the earlier, prototype versions.
Unit 710 StuG III Flamm Speilbergers says this in his book Sturmgeshultz & its variants.
"none of the ten vehicles were used in combat" "after six months doing nothing at the front they were converted back into 7.5cm gun stugs."

Units 378 and 380 Fortino Alpino Flamethrowers are probably Fougasse not flame throwers so might be removed. Italian Socialist Republic also has these.
Unit 61 L 3-33/35 first used in Italian Somaliland on 4/36 game has start date of 10/43. Start date was much closer in v13 at 6/35 also lost its LF designation in v14. Unit 346 L6 Lanciafiamme also had the correct service start date in v13 now wrong in v14.
Gives Italian Vehicle flame weapons range 30-40m
First employed in 1935 maybe this FT has something similar to the capabilities of the man pack model.

Unit 110 SS-Ki looks to have had the infantry flame weapon mounted with range less than 50m so should replace weapon 108 with 83. According to Rikugun it usually had one Flamethrower at front and then one on each side giving a total of 3 or a later version the BO from 1940 has 5 mounting points.The ball mounts could take either a flamethrower or MG so you could expand the vehicle armament into 3 MG or 3 FT or any combination therin.
SS Ki uses Type 89 Hull so armour front and sides of 5 and 3 look wrong. Rikugun has 25mm front and sides at 13mm. Type 89 gets front armour value of 3, hull side of 2. Not sure how the Tochca charge was used or actually even what it is? 8 vehicles were captured on Luzon in summer of 45 so maybe game end date of 1937 could be extended.

Unit 718 PzKfpw I Flama last seen on 11/37, game finishes on 12/40.
Two existed, one with, one without, a cmg.

The Germans, Japanese and Italians never developed a suitable napalm to thicken up and increase the range of their flamethrowers. None of their flame vehicles had a range better than about 50m. All various sources confirm this. For example from
"The effective range of German tank models was only about forty yards"

Fletcher mentions in his book
"Napalm and Fras (British Napalm) not used until DDay"
Which is relevant because for the US Navy Mk 1 flamethrower, Duration of fire was 55 seconds for gasoline and oil mixture, and 80 seconds for napalm.

The various date issue can be fixed by attaching OOB files to the scenarios.

The numbers I've used can be verified in these links and in the various books I have mentioned in the text.
