Borgs get stunned by batons and tasers.

How about this:

Advanced EMP Protection Module

While active, drains 15/second

Provides a resistance to stuns and flashes via an improved recovery time; will also make it harder to emag a borg, requiring multiple smacks with an emag possibly.

Seriosuly though borgs are already nigh invulnerable and making them stunproof and flashproof is a really horrible idea
