On locally soluble AFN-groups

Let A be an RG-module, where R is a commutative ring, G is a locally soluble group, C-G(A) = 1, and each proper subgroup H of G for which A/C-A(H) is not a noetherian R-module, is finitely generated. We describe the structure of a locally soluble group G with these conditions and the structure of G under consideration if G is a finitely generated soluble group and the quotient module A/C-A(G) is not a noetherian R-module.
