Which armies had increased in size betwen 1870 and 1914?

Between 1870 and 1914, several major European armies significantly increased in size, reflecting the militarization of the continent leading up to World War I. Notably, the German army expanded as the nation unified and adopted a policy of militarism, while France also grew its forces in response to the perceived threat from Germany. Additionally, Russia's army expanded dramatically, driven by its vast geography and ambitions in Eastern Europe. Britain, while maintaining a smaller standing army, increased its naval power and focused on a more modern military approach during this period.
