i think mines the mines can contain nano bots(for robots)
and a virus that kills the solider slowly and the only way to cure the solider
is by bringing with the groop a special unit that heals the soliders like in tiberian sun
another idea is a stucture thats for ghiant robots like an atom re-builder
that can tern enemy structures to trees but it takes 20 seconds for it to work
and to stop it you need an atom injeneere to stop its transformation
and last a normal injeneere that can turn enemy structures and robots to your property[/b]
