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.
But concern is growing that rivals like China and Russia could pick up those transmissions and jam them, change them to confuse or deceive, or track them to target the people sending and receiving them — tactics Russia and Russian-backed forces are believed to have used before.
The Pentagon has started exploring the use of laser communications systems that are harder to detect and disrupt.
