Summary
A UK-based think tank warns that Europe’s increased defense spending and weapon production, spurred by Russia’s invasion of Ukraine, is undermined by a shortage of military personnel.
European NATO members now allocate over half of their defense budgets to European-made equipment, yet critical troop shortfalls persist due to decades of underinvestment.
Concerns are heightened with Donald Trump’s return to the White House, raising fears of reduced U.S. support for Ukraine.
European leaders, including France’s Emmanuel Macron, emphasize the need for Europe to become less reliant on U.S. security support.
Using the USA as a model, the federal military maintains the specialized units that don’t have a civilian use along with training the military leadership such that it can absorb a larger army.
Individual states have active reserve military units (national guard) that have both military and civilian use. For instance, a lot of disaster response activities in the USA is performed by the national guard under state control.
From that skeleton, the US military can then fill out other units in times of war.
My guess is that an EU military would follow that structure since it has been shown to work well and the union can’t rely on France to build and fund those specialty units by themselves.
