2005 to 2010 On 18 October 2004, the OSS and DDSI were abolished during the purge of General Khin Nyunt and military intelligence units. OSS ordered 4 regiment to raid in DDSI Headquarter in Yangon. At the same time, all of the MIU in the whole country were raided and arrested by OSS corps. Nearly two thirds of MIU officers were detained for years. A new military intelligence unit called Military Affairs Security (MAS) was formed to take over the functions of the DDSI, but MAS units were much fewer than DDSI's and MAS was under control by local Division commander.
