Former US Marine 2nd Lieutenant Adam Ballard has given his excuse for his lapse in integrity, in which he cheated on a land navigation test:  everybody’s doing it, and it was the school’s fault:

Ballard admits his actions were wrong but said they were facilitated by “inordinately lax procedures at [the basic officer school]…”

Over half of the three hundred Marines in our company possessed the same information that I had and that those numbers were comparable, if not more, in all the other training companies past and present…

As noted here often, neither a “culture” that seems to encourage cheating, nor a tangible disadvantage for not cheating are excuses for making the “easier” wrong choice.
