We present a very simple form of the supercharges and the Hamiltonian of ${\cal N}{=}\,2$ supersymmetric extension of $n$-particle Ruijsenaars--Schneider models for three cases of the interaction: $1/(x_i-x_j)$, $1/tan(x_i-x_j)$, $1/tanh(x_i-x_j)$. The long ``fermionic tails'' of the supercharges and Hamiltonian rolled up in the simple rational functions depending on fermionic bilinears.
