Percentile rank
The rank of Corporal and Leading Seaman are equivalent. The next level up is Sergeant (army) Petty Officer (navy). Although the American Navy turfs in a few extra pay grades under the Petty Officer rank. On the other hand the British Navy skips the rank of Petty Officer 2nd Class and goes right to Petty Officer 1st Class from Leading Seaman. Petty Officer 1st Class is equivalent to Warrant Officer in the Army. Confused?
