Love the Iron 10th! To use an old saying, they are "All Business All The Time, serious as a heart-attack, harder and colder then a coffin nail" They are a beautifully made war machine... methodical, uncaring, unfeeling, it ain't personal. Kill, burn, move on, kill, burn, move on.
You know, the Iron Hands are my new favorite legion and chapter now. Possibly making my homebrew chapter a Iron Hands successor, the Iron Hands deserved better than most of the legions.
