sniper sentry vs auto sentry vs burst sentry

If we are taking two with us which two should we bring and what are some tips of where to place them

Auto sentry is nice for utilizing for the enemy stagger mechanic. Maybe read up or watch videos of people using C-foam on doors for alarms and placing a mine on the door. Sentrys are no longer really used behind a door while it is c-foamed. Although, every level is somewhat different so tactics involving the unique level should be considered. Consult youtube and watch videos of the level :D? Bio-tracker is great. Pretty much one of each is pretty much the average go to except for B1/B3/D1 where you need two sentrys. (Auto sentrys)

Sniper sentry is more focused on high damage. Personally I wouldn't bring this at all unless the expedition has a long corridor, however as mentioned, long corridors help a lot with the sniper sentry.

Burst sentry is also focused on damage, however this time it's more like a moderate damage. The burst also works on hallways and such. Because of this, a lot of the sentries aren't really that useful for putting outside of doors.

Since auto sentry is focused on stagger instead of damage, putting it behind a door is pretty much useless. Personally what I do is I put it a bit far from the door inside the room, and then when I'm done with the scans I would run up and kill the enemies while they're being staggered.

Really, that strategy works for all of them, as the only sentry that could really do damage behind doors was the shotgun sentry, and even then in late R3 unless you had the absolute perfect spot, it wasn't really needed.
