All the useful categories in the study of the mixed abelian groups (e.g. {\bf Warf} and {\bf Walk}) ignore the torsion. We introduce a new category denoted ${\cal A}$ which ignores the torsion-freeness and could characterize some classes of nonsplitting mixed groups with the aid of {\bf Walk.}
Classification : 20K21, 18E05.
Keywords: additive category, quotient category, splitting mixed Abelian groups.
