  The Green-Schwarz action for a non-BPS p=2 brane embedded in a N=1, D=4
target superspace is shown to be equivalent to the Nambu-Goto-Akulov-Volkov
action obtained via the nonlinear realization of the associated target space
super-Poincare symmetries. Introducing a U(1) gauge field strength as a
Lagrange multiplier, this p=2 brane action is re-cast into its equivalent dual
form non-BPS D2-brane Born-Infeld action. Following the procedure given by Sen,
the Green-Schwarz action for a non-BPS D2-brane is determined directly. From
it, conversely, the dual form non-BPS p=2 brane action is derived. The p=2
brane and the D2-brane actions obtained by these two approaches are different
in form. Through explicitly determined field redefinitions, these actions are
shown to be equivalent.
