Narrative:

During taxi-out from the gate to runway 19R at mke, we were cleared to taxi via txwys B, M, east to runway 19R at intersection V for intersection departure. Captain and first officer were conducting required takeoff briefing. Missed taxiway V and inadvertently crossed runway 25R. This runway is narrow and when accompanied by the distraction of the takeoff briefing, was mistaken for another taxiway. Tower cleared us for full length takeoff and advised no action would be taken. Contributing to our illusion that we had not yet reached intersection V was citation jet waiting for a full length takeoff at taxiway F. From our perspective, it made this appear to be the takeoff point to which we had been directed.
