6 anti-ship missiles were fired on the blockade (only 3 fired from one ship were shown) after two Vanguard class Ashkratian destroyers were sent to fire a "warning shot." The press questions the ethicality of this method, but Fleet Admiral Conners replied, "We do not intend to destroy their ships unless they do not comply, however we are not above using more aggressive methods to drive them away. These were merely warning shots."
Those green things are NOT lasers, they are anti-ship missile tracers. First time animating a battle (btw from now on, unless its a cinematic animation, all space battles should be shown from top view, not side view.)
