Question

which new - technology keeps soldiers safe during war?
wind turbines
space satellite

Explanation:

During war, smart weapons are designed to increase the precision of attacks, reducing collateral - damage and potentially keeping soldiers safer by allowing for more targeted strikes from a distance. Wind turbines are for energy - generation and not related to soldier safety in war. Space satellites have various functions like communication and surveillance but do not directly keep soldiers safe in the sense of on - the - ground combat safety. Electric batteries are power sources and not a technology specifically for keeping soldiers safe during war.

smart weapons
