Intruders

Sviblov is convinced Clear Sky is spread too thin to provide immediate support in Zaton. After several attempts to convince him using intel gathered in previous quests, the base will be attacked by the military.
==Walkthrough==
Eight soldiers will be in the initial assault. They'll be outnumbered and easily overrun by the Clear Sky forces, but more soldiers are closing in to the east. Head to the farm to provide support.
As you approach, more Clear Sky stalkers will spawn in to help you deal with the large incursion of 30 soldiers over two separate spawns. They'll eventually all be wiped out as you clean up stragglers. Beware of the three RPO-A users hiding in the reeds - they can somehow rapidfire their launchers up to four times in a row.
After the last soldier has been taken out, a message will come in about two attack helicopters approaching the farm. Sviblov will advise you to pick up a stash containing a Barrett M95 and ammunition for it in the westernmost house with the boats, but it's not required to down the helis.
After taking care of both helicopters, bring the Barrett back to Sviblov and he'll agree to send his nearest squad to Zaton to join our forces.
==Notes==
*As always, the attack helicopters can be destroyed using a smallbore rifle with a couple of quick bursts to the tail rotors. Save the expensive ammunition for other applications.
*The dead Clear Sky stalkers are a good source of Serum and the otherwise rare Guardian of Clear Sky suits needed for Arnie's chain.
