It's very hard to fight a war in Singapore! Say we place a sniper on everybuilding, they will have a freaking time ti find the sniper! Say the fight is in the CBD area, where there can be many ambush laid out for the enemy! HAHA!@ I tell you, the enemy would rather bomb the whole island flat then take it house by house, which may take a few years, given the number of high-rise buildings in singapore.
