During the first Iraq War, before America entered Iraq, the first thing they did was deploy electromagnetic interference with electronic warfare aircraft. The second step was sending planes equipped with anti-radiation missiles to clear Iraq's radar. Only after opening up a radar-free pathway did bombers and fighter jets enter en masse to start bombing.
Modern warfare is already in the era of electronics; the invisible, intangible electromagnetic signals have a far greater impact on the battlefield than people imagine.
When he realized the walkie-talkie was no longer working, Gao Yang knew that people who meant business had arrived. Russian Special Forces' first action is never electromagnetic interference but rather throwing bombs, whereas Americans come knocking with electronic interference first.
If the Americans come knocking but haven't deployed electromagnetic interference, it can only mean one thing: the enemy is too backward to qualify for electronic warfare treatment.
