The ongoing war in Ukraine has provided Finnish reservists with significant insights on drone warfare, particularly the implications for survival on the battlefield. Jarmo Nieminen, a former lieutenant colonel and author, highlights the necessity for soldiers to constantly be aware of the traces they leave during combat, such as heat signatures, which drones can detect. This awareness introduces a new layer of complexity to staying concealed and maneuvering in the field.

Nieminen, who has been closely monitoring the ongoing conflict for four years, initiated a series of articles at the request of reservists to inform them about the realities of modern warfare from a soldier's perspective. His focus has been on survivability, which has become a primary concern for Finnish reservists. The discussion centers on the tactics of covering one's heat signature, hiding waste, and avoiding leaving identifiable marks on the battlefield to prevent detection by enemy drones.

Constant vigilance and adaptation to new warfare technologies, such as drone surveillance, are emphasized as critical skills for modern combatants. Nieminen’s insights suggest that as warfare evolves with technology, training for reservists must also adapt to prepare them more effectively for potential future conflicts, highlighting an urgent need for updated tactics and strategies in military training programs.
