The strengthening of NATO FPF is the systematic process that by mid-2022 is in the third stage of development. During the first period (2004–2013), the naval and first air military groups have been created. At the second stage (2014–2021), the structure of staffs from corps and division levels has been established. The ground troops of FPF have begun to deploy with some delay in time and especially in level from the staffs. The first component of FPF ground troops are the US forces in national status, the second one is multinational battalion tactic groups (BTG). The staffs created the structure of large perspective architecture of NATO FPF. It has rapidly begun to fill with troops since January 2022, which marked the beginning of the third stage.
