South Korean military: ”We've accumulated technology and experience in the 'balloons' that fly in from the North”... ”Accuracy has also improved”

North Korea has launched "filth and garbage balloons" toward South Korea dozens of times this year, leading South Korean military authorities to conclude that "North Korea has accumulated a certain amount of experience."
Lee Sung-jun, head of the public relations office of the South Korean Joint Chiefs of Staff, said at a regular press conference on the 2nd, "There has been a slight increase in (North Korean) trash balloons flying into Seoul," and "More than 30 times."
"They've been flying balloons for a long time now, so they've accumulated technology and experience, and the accuracy has improved in some areas," he said.
"They've flown to northern Wondo in the past, but recently they've been flying toward Seoul, which makes me think they may be doing it on purpose."
