Some game stats for that helmet I posted pics of yesterday. In DC terms this is pre-Crisis, Silver Age stuff. The capabilities are conjectural but seem like what future cops would have.
Science Police Helmet (Major Gadget)
15 points Armor (head only); Police-Band Radio; Global Positioning System; Anti-Glare Visor and Ear Protectors (+6 bonus to checks to avoid the effects of Flare attacks and Flash-Bang Grenades.)
These stats are for the free Tri-Stat dX game, but will also work for BESM. To use it with BESM 2nd ed. change the "+6" to a "-3".
