Like Father like Son?

I’ve seen a situation recently and it just seems kind of wrong. Not that anyone has done anything wrong but I don’t think a parent and their kid should be in the same unit especially when the Father/Mother is in a senior ranking person. Sometimes I think this can cause this Soldier to receive preferential treatment. I don’t know that this has happened but it could happen. I was a little shocked when I saw a Father and Son in the same Battalion. I don’t know if there has been any preferential treatment but I don’t think they should be in the same unit.
