We have just entered crunch time. You know what I mean if you have deployed before. It is the time when everyone becomes what they truly are. If they are assholes in "real" life then they are assholes now. Let me explain it differently.
Some people will act extra nice to one another in the first few weeks thinking that this behavior will give them something, i.e. friends, bennies, what ever. After this endures for awhile, natural human behavior kicks in and whatever "type" of person they are normally, will be the person everyone sees.
