  We give a moduli description for the ramified unitary local model of
signature (n-1,1) with any parahoric level structure when the residue field has
characteristic not equals 2, confirming a conjecture of Smithling. As
applications, we can present moduli descriptions for: (1) ramified unitary
Pappas-Zhu local models with any parahoric level; (2) the irreducible
components of their special fiber with maximal parahoric level; (3) integral
model of ramified unitary Shimura varieties for any (quasi-)parahoric level.
