Nice crew trainer too, together with the M3 light, Tetrarch, and LTP. The T127 and LTP are pretty good tanks really. Just got a rubbish reputation by the hordes that tried to use them when gifted, and naturally failed. Camo base values are 18, and 20. Add a cammo net paint job, and vents and crew training means that a T-127 vs pimped out T-127, is you'll spot him at 344m, and has to get within 195m to see you. Similar for other tanks too.
I take out my crew in the light tank premiums to train them up. Rarely get a bad game.
