Between a rock and a hard place

A Monolith sniper using some advanced armor started to operate at night at Radar recently. Bullets don't do much damage to him! Syak wants you to try sneaking up to him and killing him with a Sledgehammer.
== Walkthrough ==
At 1:00AM, speak to Syak while having a Sledgehammer in your inventory to start this quest.
The sniper appears at the top of the [ sniper hut]. You have the following options to reach him:
* Use any of the suits that conceal your footsteps. Avoid his view cone.
* Use a cloaking exoskeleton. (see Stealth#Cloaking_exoskeleton).
* Avoiding his view cone, approach him. Start crawling when you're too close. Start jumping in place and moving only while in air to get at the point blank range.
* Throw a smoke grenade or a flash to make him panic.
* Make a noise and lure him out, then circle him around.
After getting within the point blank range, murder him with the sledgehammer. The sniper is armed with a LR-300ML "Sniper", and drops it in full condition.
Return to Syak for your reward.
== Notes ==
* Sledgehammer should be in better condition than 15% to be valid for the quest.
* It is better to arrive in Radar early and clear out anything that would cause issues before speaking to Syak. Psy-dogs and blind dogs that live near the sniper will interfere heavily if not taken care of.
