KSS Liberty

Just after the survivors were rescued, the Liberty managed to intercept the following radio call:

"We confirm the existence of a dumping site 10 kilometres away from your position. Get there ASAP and verify if its contents are useful for our cause. If you find any kind of ordnance (mines, artillery shells, etc) or weapons, mark the site as positive in the maps. The Federation is probably also dumping chemical and biological weapons, so look out for them too. Also, even if you are discovered, don't start the self-destruct secuence; we can't lose another submarine. Command out".

After the call ended, the submarine's Executive Officer (the Captain had died during the sinking, making him the highest ranked officer in the submarine) was taken to be interrogated.
"So, why are you searching for the dumping sites?" said David Jarić, the Captain of the Liberty.
