The Cold War pattern behind an Irn-Bru camouflage joke

What is a Berlin-inspired Irn-Bru camouflage scheme?

It is the British Berlin Brigade urban pattern recolored with Irn-Bru orange and blue, a hobby joke rather than a historical scheme.

The answer begins with the real Berlin Brigade camouflage used by British armour during the Cold War. Its sharply divided blocks were intended for an urban environment and used a restrained military palette. The proposed Irn-Bru version is a modelling joke that substitutes the drink's orange and blue branding, not an authentic historical scheme. The panel also notes that the angular pattern is notoriously painstaking to paint on miniatures.
