Shaka sign (Jumbo) / Джамбо (Concept) for Pony / Illustrious

The shaka sign, sometimes known as "hang loose" is a gesture with friendly intent often associated with Hawaii and surf culture.

It was adopted by mercenaries in Africa, where it was called "jumbo". The militaries of different countries, including the Russian military, show it as a greeting among themselves or as a show of force.
