Kay's M4 Sherman and Darjeeling's Sherman Firefly

Kay

Darjeeling, what in Sam Hill are you doing to that Sherman?

Darjeeling

Improving upon perfection, Kay. The 75mm simply won't suffice against the Tigers.

Kay

Five engines tied together? That's crazy talk! And what's with that rectangle cutout?

Darjeeling

The 17-pounder requires space for recoil. This modification will give us the firepower to penetrate their frontal armor.

Kay

But turning the turret sideways? That'll throw off the whole balance! The recoil might flip us!

Darjeeling

Calculated risk, old sport. Sometimes revolution requires breaking a few rules.

Kay

Darjeeling... the base commander is coming this way. And he's got MPs with him!

Darjeeling

(How delightful. It appears the tea has been served.)

Darjeeling

(Let's see how they react to the official requisition forms I've... creatively acquired.)

Kay

Commander Bradley! Sir, we were just—

Darjeeling

Good afternoon, Commander. Care for some Earl Grey?

Darjeeling

(The look on his face is absolutely priceless.)

Kay

Well I'll be... you sly fox. You had authorization this whole time?

Darjeeling

Project Firefly, authorized by Allied Command. Section 7, paragraph 3.

Darjeeling

"Experimental modifications to Allied armor permitted for field testing."

Darjeeling

(Of course, the signature is a week old. The modification was already complete when this arrived.)

Kay

Darjeeling, you magnificent rule-breaker! Even the paperwork's backwards!

Darjeeling

(Synchronizing five engines is like conducting a symphony of controlled chaos.)

Kay

Darjeeling, that torque reading's climbing past redline!

Darjeeling

Three... two... one.

Kay

Sweet mother of pearl... she's lifting off the ground!

Darjeeling

(The Earl Grey tastes better when accompanied by the sound of five synchronized engines.)

Kay

The fuel lines! They're burning up—if this thing goes critical—

Darjeeling

(Time to see if my little modification to the modification works.)

Kay

Wait... is that another engine I hear? But from where?

Kay

(Time to show Darjeeling what a standard Sherman can do.)

Kay

Damn it! Not even a scratch on those Tiger plates!

Darjeeling

Allow me to demonstrate proper British engineering.

Darjeeling

(The stabilizer modification should compensate for the 17-pounder's recoil.)

Darjeeling

Observe the penetration capabilities of a properly modified weapon.

Kay

Holy... you actually punched clean through! But the turret's sideways!

Darjeeling

Revolutionary tactics require revolutionary thinking. Shall we test the Tiger itself next?

Kay

(Is that... actual Tiger tracks heading this way?)
