Among the solutions of string theory and supergravity which preserve somefraction of supersymmetry, the best known are those that leave one half of thesupersymmetry unbroken, and there is a large number of field theory models withthis pattern of supersymmetry breaking. However, a lot of brane configurationsexist which preserve only $1/4$, $1/8$ or more exotic fractions ofsupersymmetry, and field theory side of these systems remains largelyunexplored. To find whether the formalism of nonlinear realizations is usefulin construction of models of this type, we consider the systems of some $N_0$scalar and vector $N=1$, $d=3$ Goldstone supermultiplets. We find that it ispossible to construct an $SO(N_0)$ invariant theory of $N_0$ scalar multipletswith $N_0$ broken supersymmetries. For $N_0=3$ or $N_0\geq 5$ its action is notof Nambu-Goto type and its structure remains universal for arbitrary $N_0$. Thecases of $N_0=1,2$ correspond to the membranes in $D=4$ and $D=5$,respectively, while for $N_0=4$ some arbitrariness in the action remains, andwith proper choice of parameters, it is possible to obtain the action of themembrane in $D=7$ in the bosonic limit. It is also shown that the $SO(N_0)$invariant action of $N_0$ vector multiplets with $1/N_0$ pattern ofsupersymmetry breaking does not exist for arbitrary $N_0$.
