Estonia shifts to 'active defense' doctrine with planned deep-strike posture

The post describes Estonia adopting an 'active defense' concept: forward-deploying its 1st Infantry Brigade closer to the Russian border and planning early strikes into Russian territory using future long-range rocket artillery (HIMARS/Chunmoo). While much is framed as aspirational and dependent on future deliveries, the doctrinal shift from partisan-style defense to immediate border defense and deep fires is a notable change in posture worth tracking.
