5:52AM, Alyeskan Biological Research Base.
A lone sniper approaches the base with a silenced 7mm sniper rifle in hand, a remnant of the old terran Russia, akin to something Irajinia or Nirvozk would use. He approaches with calm, and hides in a bush until the guards watching the entrance go away.

Now was the fun part. The sniper, intending to cause confusion and friendly fire, throws tons of shrapnel grenades and smoke grenades into the midst of them. They start firing wildly into each other, and the few that notice the sniper are shot down, their brains blown out by hot lead.

The sniper approaches the main building, which had the door wide open, and blew the remaining guard's brains out with his special Desert Eagle, and walked up to the bunker entrance. He took out a small welder and welded it shut, the scientists trapped inside. He stepped up to one dead body of the only scientist above ground, and he pulled a vial, and a USB drive out of his pocket.

When the confusion was all over, and the dust settled, and the extraction teams sent in, there was no trace of the unknown terrorist. The only thing left was the welder, no fingerprints, a empty sniper rifle, no fingerprints, with a Irajinian signature burnt in, and a stuffload of dead bodies.
