SEOUL, South Korea (AP) -– South Korea says it will deploy more fighter jets, helicopters, artillery and advanced spy aircraft to better prepare for potential attacks by North Korea.

The plans are among a package of measures announced Tuesday aimed at building a stronger, more efficient army in the wake of the sinking of a South Korean warship and North Korea's shelling of a South Korean island last year.
Fifty South Koreans were killed.
Defense Minister Kim Kwan-jin says the attacks left the South Koreans with ""enormous shocks and scars"" but gave the military a chance to review its readiness to North Korean provocation.
Other measures include streamlining the top military brass and creating a joint military command tasked with defending front-line islands.
