Destroy the first sentry without taking any damage in Chapter 2: Freedom

You'll know it as soon as you see it! The sentries are these tall looking security guns
with Blue scans coming out if its top.

When you reach the first one, Boone (one of the guys with you) will say something
about it and will tell you that you can get close to it without getting detected.

What you need to do it is get from cover to cover until you reach the sentry to be
able to destroy it.

NOTE:
Even if you got seen by the sentry you can easily avoid its bullets by going to cover
as soon as it sees you
