Big MT was responsible for one of the most breathtaking research endeavours back before the War. Endeavours that at the same time often violated basic human rights. The results of their research were sometimes sold to non-governmental parties in exchange for money.
However, as unethical as their operations could be, their achievements were groundbreaking. Despite that fact, they never reached widespread deployment due to issues with cost, efficiency or simply greater influence of certain parties such as the other defense contractors West Tek and the construction of Liberty Prime.
