Rocket Sentry

Overview
Rocket Sentries are rare, dangerous variants of the default Combine Turret that, as the name implies, instead of firing pulse rounds, fire large, heavily damaging rockets at whatever they see.

They are identical in appearance to default Turrets, which can catch the unprepared player off guard rather easily.

Rocket Sentries first appear in Nova Prospekt. The first Rocket Sentry the player encounters is behind a locked gate near a control station. Afterwards, they will rarely replace random turrets.

Despite what one may think, Rocket Sentries do not fire slowly. They are actually rather quick, firing approximately 2-3 rockets per second, which can, obviously, cause massive damage to anyone in the way.

Rocket Sentries behave identically to default Turrets, although they may stop firing if their target is dangerously close.

Tactics
-If a Rocket Sentry has spotted you, immediately get to cover, and be sure to back up. Even if you are able to hide, the rocket's blast radius is still able to damage you.

-Keep in mind that the rockets fired by the Sentry cannot be caught by either the Physgun or Gravity Gun. They also cannot be replicated by the Stuff Launcher.

-The Rocket Sentry may stop firing if it's enemy is particularly close by, allowing one to easily knock it over.

-As with all Turrets, you are able to knock it over with the Physgun or with a prop fired by the Gravity Gun. You can also toss a grenade at it, preferably around a corner.

-While Rocket Sentries are rare, be very careful around any Turret you see. They are quite capable of being either a Rocket or Laser Sentry, while having the exact same appearance.
