  We present interacting massive N=1 vector multiplet (VM) in nine dimensions
(9D). Due to the identically-vanishing mass-term m(\Bar\lambda \lambda ) \equiv
0 for (symplectic) pseudo-Majorana gaugino in 9D, we employ unconventional
technique to give masses to fermions. In 9D, we consider the gauge group G for
the VM (A_\mu{}^I, \lambda^I , \varphi^I) (I = 1, 2, \cdots, dim G), where G is
the Yang-Mills gauge group, and the gaugino \lambda^I is a pseudo-Majorana
spinor. We break G by shifting the scalar \varphi^I, so that the gaugino
\lambda^I as well as its super-partner gauge boson A_\mu{}^I will get the same
mass. The scalar \varphi^I plays the role of a Nambu-Goldstone boson absorbed
into the longitudinal components of A_\mu{}^I$, making the latter massive as a
super-Proca-Stueckelberg mechanism. We also show that a similar method can be
also applied to N=2 VMs in 5D.
