The Grizzly Firefly

The introduction of the Grizzly came into reality as the American M4A1 Sherman Medium tank was at the time the most modern and successful medium tanks that the allies were producing at the time and would become the “standard” medium tank for the allies during 1943-1945.
The Grizzly is a Canadian made M4A1 Sherman, they were produced at the Tank Arsenal, Montreal Locomotive Works in Montreal, Quebec. There were some differences between the USA M4A1 Sherman and the Canadian made Grizzly which were the additions of a two inch smoke mortar, #19 Wireless set, and changes to stowage and a few other small things to follow Canadian and British standards.

Other additions that happened later on was the introduction of casting the applique armour that was introduced in tanks that were made further in the production process. Included with the extra plates casted into the hull the tracks were switched out for CDP tracks.
There was also version of the Grizzly without any applique armour.
The production of the Grizzly tank stated in August of 1943 and ceased production at the end of 1943. Due to USA’s production line being able to produce enough tanks that the need for Canada to producer their own versions became unnecessary.

In total there was only 188 Grizzly’s made.

There were also other vehicle created using the chassis of the grizzly including: Grizzly Kangaroo’s, Grizzly Firefly, Skink A.A, and the Sexton Mk.II.

The main focus for this suggestion is for the Grizzly Firefly hull number 160258. This was a 1 off made by Canada. from what I can find United Kingdom sent 3 firefly turrets to Canada in 1945 for training. one of these turret was fitted to a grizzly hull and was used at Camp Bordon which where it currently stands to this day.

Even though the Grizzly Firefly never saw service Canada used Sherman Firefly’s overseas during the war.


The Grizzly program came into being in the spring of 1942 when members from the United States, Canada and United Kingdom got together to discuss maximizing a possibility of standardization for allied tanks. From those talks the M4 was selected as the tank to standardize throughout the armies, but with that they would be allowed to make some changes to the design to fit their standards/ policies better. On March 26th, 1942 representatives from Canada and the United States came together for a meeting to discuss that Canadian production capacity should be used for the production of the American M4A1 tank, which the Canadian representatives agreed with as the weight for the M4 was around the same as the Ram tank that Canadian tank production was currently producing, changing to the M4 would also fall in line with the agreement made in the previous meeting for standardization.

The N.D.H.Q. initial proposed the name “Buffalo” for the Canadian made M4A1 tanks but it was pointed out by General Officer Commanding-in-Chief of the First Canadian Army that the buffalo was a heraldic animal of the British Armoured Divisions and that the name “Buffalo” should not be used. He then gave his recommendation to name the tank “Grizzly” as it represents Grizzly bears which can be found in Canada. His recommendation was accepted by the N.D.H.Q. The tanks also recieved some modifications from the standard American made M4A1 as stated above.

Would love to see even if it was basically the same but with a different engine

Seems like a good squadron low tier vehicle in UK or a premium/BP in US tree. I don’t feel like it would make for a good event vehicle with the new system like most low and mid tiers. Also reason why i would not put it as premium in UK is because they already have a firefly there, only option would be if they took it our of sale and made it a rare vehicle.


+1. I’d like to see it in game no matter how they bring it in. I agree with @Neobushido on placement.

+1 for a future Canadian TT.
