A sentence for rape

Hawai'i Army Weekly, a military website, reports that an officer convicted of rape was sentenced to 18 months' confinement, along with a dismissal, total forfeitures and, oh yes, a reprimand. This was not the result of a pretrial agreement. The case was tried to a jury, so the sentence was determined by the members. Eighteen months? There's got to be a story behind this. Please comment if you know if (use your own name when posting).

In another 25th Infantry Division case, a noncommissioned officer was acquitted of sexual assault. That case was also tried to a jury (which included enlisted representation).
