Points cost, very approcimately per MEQ-model in the squad.

3p Red dot laser sight: Forces your target to reroll successfull coversaves from area terrain.
3p Full Metal Jacket ammunition: Forces your target to reroll successfull coversaves due to intervening models from that faction. Your allies can still be in the way for your shots.
3p Motion tracker: Forces your target to reroll successfull coversaves if they moved last turn.

I imagine these could be interesting. Feedback please]]> http://www.dakkadakka.com/dakkaforum/posts/preList/233442/614994.page http://www.dakkadakka.com/dakkaforum/posts/preList/233442/614994.page GMT
They are overpriced because they will add 30 pts per upgrade to a full squad of marines. They are overpowered because rerolling a coversave means you kill 75% of what you hit on average instead of 50% (assuming 4+ coversave), and clearly to get any mileage out of these, if you dont know the list you are playing before you build your list, you are going to need all of them.

Edit; in some ways the overpricing and situational usefulness helps counter the overpowering nature, but in others they are still a thousand dollar glass hammer. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/233442/615784.page http://www.dakkadakka.com/dakkaforum/posts/preList/233442/615784.page GMT http://www.dakkadakka.com/dakkaforum/posts/preList/233442/615913.page http://www.dakkadakka.com/dakkaforum/posts/preList/233442/615913.page GMT http://www.dakkadakka.com/dakkaforum/posts/preList/233442/615948.page http://www.dakkadakka.com/dakkaforum/posts/preList/233442/615948.page GMT
