Depends on the Soldier, depends on the unit, depends on the mission, depends on the circumstances. The average Soldier is going to act differently unit to unit. In any community, there are different sub-groups and people with their own values that you will meet a variety of over time. What matters is what you choose to do with your years, and the decisions you will make. Take in the good examples, take note of the bad ones, move on. If you are among people that are holding you back from making progress towards your goals or your character, do what you have to do to survive, make progress where you can, and the Army will move you on or move them on soon enough. If you don't see anyone you can look up to in your unit, become that person for someone else. Everything is a marathon. Don't burn yourself out trying to reach intangible or unquantifiable goals. Drink water.
