Narrative:
We were cleared to taxi from our gate to runway 31R des moines. As we taxied out the captain elected to use taxiway B to intercept taxiway D. As we approached taxiway D, the captain started a right turn (northbound) on taxiway D towards runway 13L. I challenged his decision and told him to turn left (sbound) on taxiway D. He seemed disoriented, and repeated his decision to turn right. At this time the ground controller told us to turn left on taxiway D. Our plane was facing northwest on taxiway D at B/D intersection when the captain started an abrupt and sharp turn to the left to proceed sbound on taxiway D. The nosewheel left the taxiway pavement and sank into the mud on the southwest corner of B/D intersection. Supplemental information from acn 390490: all further aircraft movement stopped. No injuries. Only aircraft damage was nose gear mud deflector.
