Battlecomm T&T is the Targeting and Tracking system as made by TEK; It's a heavily-radiation shielded Communications and Tracking system that is highly desired for command 'mech purposes because it's damn near Lostech in size, instead of being comparatively bulky, and can ignore things like magnetic interference, radiation, or ionization (eg. PPC hits) without ill effect.<br/><br/>The Targeting and Tracking aspect is a seperate system that is known to be heat-resistant, making it easier to maintain a target lock while overheating; Hot-runners such as the Marauder love it because of that.
