Patchett Mk.I Authenticity Buff

Hello bajtársak and fellow forumdwellers,
Today marks the one year anniversary of the Patchett mk.I getting added to the game. It was added exactly one year ago on 31st of October 2025.

The Patchett mk.I was a British prototype that had reached combat trials during the time of the Second World War, about a hundred submachine guns were deployed with the 6th Airborne Division in 1944.
Later iterations of the Patchett, adopted under the Sterling designation, were mass-produced and utilised by numerous militaries, police and security forces across the globe. The 1A1 variant remained in production until 2010 and is still in use in India.

The Stats and the problem

Here are the stats of the Patchett, the STEN mk.II, the Lanchester and finally the MP40 as these are related to the discussion.
The damage, damage drop over distance, reload, muzzle velocity and recoil are the most relevant differences now.

Submachine Guns			Damage				Reload Timings (s)			Statcard Recoil			Effective Recoil			Moving Spread Increase
Weapon Name	Obtained	BR	10m	100m	Velocity	Magazine	Reload	Alt Reload	Rate of Fire	Vertical	Horizontal	Recoil Control	Vertical	Horizontal	Dispersion	While Aiming	Hipfiring	Visual Recoil	Recoil Dir	ADS Speed	Recoil Offset	Sprint Factor	Weight	Additional Info
Patchett Mk.I	BP/Chests	II	6.8	3.4	370	32	2.1	1.7	690	33	16	0.3	10	5	0.71	0.0	15.0	0.7	0.4	0.8	0.3	100%	2.8	32/128
Sten Mk II	20000 RP	I	6.6	3.4	370	32	2.3	1.89	630	28	17	0.3	8	5	0.81	0.0	15.0	0.7	0.4	0.8	0.3	100%	4.0	32/128
Lanchester	58000 RP	II	6.8	4.0	400	32	2.3	1.8	690	30	11	0.4	12	4	0.71	0.0	15.0	1.6	0.1	0.8	0.3	100%	5.2	32/128
MP 40	100000 RP	II	7.0	4.0	400	32	2.1	1.71	630	27	9	0.3	8	3	0.70	0.0	15.0	1.6	0.35	0.8	0.3	100%	4.7	32/128

The only characteristic the game gets right at the moment is the recoil.
The Patchett is an extremely light submachine gun with 2.8kg and the folding stock and side-mounted magazine don’t help either. The uncomfortable and fairly high recoil for a 9mm gun is accurate. However this downside is hardly balanced out and the Patchett is an unremarkable gun that offers no advantages over the Lanchester besides slightly faster reload.

Correction for the Patchett

The main issue with the Patchett is that it was added as a buffed up STEN mk.II, sharing muzzle velocity and damage with it, however the STEN family and the Patchett are not related and in-game representation is simply wrong.
The STEN guns were designed to use British 9mm mk.IZ bullets that are fired with ~1200 f.p.s. (about 365 m/s) muzzle velocity while the Patchett used 9mm Mark 2Z ammunition that achieved 1300 f.p.s. (~396 m/s) with submachine guns (data taken from Imperial War Museum - 25/10/2026).
A Sterling L2A3 (closest relative of the Patchett with recorded muzzle velocity) with more advanced measuring techniques performed only 20 fps worse than the WW2 expectations with the same ammunition. That is still a tiny bit more than 390 m/s, so giving the Patchett a muzzle velocity increase is more than reasonable.

9mm submachine guns with 400 m/s muzzle velocity in-game have the same damage drop over distance, since the Patchett would be very close to that with its 390 m/s, it would be reasonable to give the Patchett the standard 9mm damage of 4.0 damage at 100m instead of 3.4 damage.

Fixing the muzzle velocity and damage over distance does not make the Patchett unique, it still needs something other British submachine guns cannot offer: a small damage buff from 6.8 to 7.0 damage at 10m. This is the change that will truly set the Patchett apart from the Lanchester and any STEN variant.
The MP40, PPS 42/43 and Király 39M already benefit from slightly higher damage, reflecting their more modern designs. Giving the Patchett 7.0 damage would therefore not be unprecedented, nor would it undermine the MP40’s identity.
The MP40 has noticeable less recoil that makes it more suited for medium range combat than the Patchett, which would be more CQC oriented with its marginally higher fire rate.

Finally, a tiny debuff:
The fire rate is currently 690 rpm (implying that the default is 600), however during the 1944 tests, it was found that the average fire rate of the Patchett mk.I was only ~580 rounds per minute which would mean a 670 rpm fire rate in the game instead of 690, not a big deal, but would ensure that the Patchett has unique stats and is an alternative next to the Lanchester and not a direct upgrade.

Changes:

muzzle velocity increase from 370 m/s to 390 m/s
damage increased from 6.8 to 7.0 at 10m
same damage drop over distance as other 9mm guns (4.0 damage at 100m)
Fire rate reduced from 690 rpm to 670 rpm

The Patchett: From Wartime Compromise to Post-War Excellence

As the resident Commonwealth main, and something of a British small-arms enthusiast, I feel rather obliged to throw my hat into the ring on this one. Indeed, I might as well be known around here as “that one Patchett obsessed bloke,” and I wholeheartedly accept that assignment.

The Patchett represents the culmination of Britain’s rather reluctant love affair with the submachine gun. From pre-war scepticism as ‘gangster weapons’, through the expensive Thompsons and Lanchesters, to the rough-and-ready expediency of the Sten, the British journey was one of necessity, improvisation, and hard-earned experience. The Sten, designed by Enfield’s Shepherd and Turpin, was ultimately an exercise in simplification: taking the Lanchester and stripping it down to produce something cheap, practical, and easily manufactured. Even the soldier-oriented Mk V remained a refinement of a weapon designed first and foremost around wartime expediency.

The Patchett, however, was something else entirely.

George W. Patchett, an engineer with the Sterling Armaments Company and familiar with the Lanchester’s design and manufacture, had a rather different ambition. Recognising that the Sten could hardly remain Britain’s answer to the submachine gun indefinitely, he sought to develop something more suitable for the future: he started with the Lanchester and set about producing a more compact, lighter, and more comfortable weapon for the soldier. The Patchett was not another attempt to recreate the Sten; it was an attempt to move beyond the very compromises that had made the Sten necessary.

Yet in Enlisted, it has been treated as little more than another Sten gun, a gun it is developmentally unrelated to; saddled with the same 370 m/s muzzle velocity, originally starting with 6.6 damage and the associated damage drop-off yet remains. Given its distinct development, Lanchester ancestry, and the ballistic characteristics of both its Lanchester predecessor and later Sterling successors, this hardly does the weapon justice.

For the Patchett was not the end of a dead-end wartime experiment, but the beginning of something better. Its development would culminate in the post-war Sterling (indeed, the Patchett was merely the “Mark 1” of the Sterling line of five main Marks). These went on to serve Britain and the Commonwealth for decades, earning a distinguished reputation and service record around the world.

From pre-war dismissal, through wartime improvisation, to post-war excellence - the Patchett has a development story few items embody quite so neatly, this distinctly British journey.

The Patchett deserves more than a forgotten place in the event roster, with statistics inherited from a weapon it was never simply a copy of. It deserves its own identity, its own gameplay purpose, and a representation worthy of its place in British small-arms history.

After all, if we’re going to have the Patchett in the game, we might as well do the old girl justice.

That’s been all from me; if asked, I could talk a little more about the wartime service history of the Patchett itself - or rather, how little we know about it. It is a rather interesting topic to discuss, especially around the Battle of Arnhem.

Yours sincerely,
Lt. Ogge King, 3rd Experimental Tea Infusion and Small Arms Appreciation Company, Home Guard (Reserve)
God save the King, and Rest in Peace George W. Patchett.

Hehe… ‘JAWA’… the joke writes itself…

PS - I almost went through an entire Patchett message without mentioning the E-11 Blaster, let me rectify this near-mistake here at the end.

Thank you for the short endorsement letter.
The Patchett mk.I has been disappointing for long enough, the patriarch of the Sterling family being treated as a light STEN is blood boilingly infuriating for me.

Also
FOR THE EMPIRE!

I’d rather it go back to br1, but this would be great if staying put

Its obviously nowhere near as good as the Type 100 (early) which has became the best BR II SMG since its fire rate was changed, however it is as good as other BR II SMGs (being very much similar to the MP38).
Unlike Patchett which is in an awkward position between being too good for BR I, but being a little weak and very uninteresting for BR II. Buffing the Welgun might turn into a buff trap where we must buff all comparable guns as well (MP38, M3A1 and a probably a bunch of premium, event and BP guns).

Another issue that a Welgun buff would raise is the position of the OG-43. Both Welgun and the OG-43 are unique to BR II paratroopers and the OG-43 is already significantly worse than the Welgun.

Seems more trouble than its worth, especially considering that paratroopers have access to many other guns through their loadouts and the squad comes with 6x SMGs which is the most you can get with a squad (excluding some select vehicle squads)
