As the Pentagon reorients toward great-power competition with adversaries like Russia and China, its preparations go beyond learning to ski and practicing to drive across Europe.
US military units rely on wireless networks and radio-frequency communications to talk on the battlefield, sharing intelligence, targeting data, and orders.

The Pentagon has started exploring the use of laser communications systems that are harder to detect and disrupt.
