This came up in another thread talking about Lyran 'mechs.
The Thunderbolt TDR-17S is first mentioned in the fluff in the Battlecorps entry on the -11SE:
http://www.battlecorps.com/BC2/news.html?article=439In that article, this variant is described as a "sprinter," with MASC. Though it's not specifically tagged as the -17S, the other design elements (weapons, gyro, engine, etc) are consistent with it.
However, the MUL and Record Sheets: 3085U Project Phoenix show this design as having TSM.
Is there another source for this 'mech? Does it have MASC or TSM? Do we have a zombie sprinter or zombie brawler here?
Thanks!
