off the wall question

Okay, I have 12 MIB ESCI NATO Pilots and Ground Crew boxes (don't  ask)
that 
have 1/72nd plastic figures.  Thinking about them as human or  humanoid 
"militia" force.  I would need rifles/etc to add to the figures to  make
them 
'combat capable' figures.  Any ideas about a source of 1/72nd  small
arms/etc?
 
Gracias,
