I don't know why the RSN even bothers to hold live firing exercise. As far as I am concerned, any local small vessel manned by dark skinned locals from Indonesia or Philippines is a high probability pirate candidate, which would make the South China Sea and Straits of Malacca a target rich environment. ALl they have to do is sail around in international waters and shoot any such vessels whenever they feel like it. i bet piracy will drop to zero. And they would be the bestest naval marksman in the SEAsia.
