Just days before a new quasi-civilian regime assumed power in Naypyidaw on March 30, Lt-Gen Thura Myint Aung was sacked from Burma's military for refusing to accept a new civilian post as Minister of Defense. It was a surprising move that abruptly sidelined a rising star: Myint Aung was popular among the army's rank-and-file, and had even been tipped to become the commander-in-chief of the armed forces under the new government.

But Myint Aung's sudden removal was just the first in a series of changes at the senior levels of the Tatmadaw, or Burmese military, leadership since junta supremo Snr-Gen Than Shwe and his deputy, Vice Snr-Gen Maung Aye, transferred their respective commander-in-chief posts to Gen Min Aung Hlaing and Lt-Gen Soe Win.

In mid-May, the Tatmadaw held its first triannual meeting under the new administration of President Thein Sein. According to leaked information from the military, there was serious disagreement among commanders concerning a number of issues, including ongoing armed conflicts in ethnic areas and the economic struggles of ordinary soldiers and their families.

About two weeks after this meeting, the War Office began a reshuffle of regional commanders affecting six Regional Military Commands (RMCs). These included Rangoon commander Brig-Gen Tun Than, who was moved to the Southern RMC in Taungoo; Brig-Gen Soe Htut, who  was moved from Taungoo to the Eastern Regional Military Command in Taunggyi; and Brig-Gen San Oo, who was shifted from Taunggyi to Rangoon.

However, three days after the regional commander reshuffle, Tun Than was forced to retire from the military. Although no official reason was given for his resignation, the Tatmadaw's military intelligence arm, the Military Affairs Security (MAS), spread rumors among political sources and businessmen that Tun Than had been removed for corruption.

About two weeks later, Maj-Gen Tin Ngwe, the chief of the Bureau of Special Operations-5 (BSO-5), which oversees the Rangoon RMC, was also forced to retire. In this case, too, the MAS  hinted that he was sacked for corruption. He was the highest-ranking military official to be fired since Myint Aung was forced out in March.

The resignations of Tin Ngwe and Tun Than came as a surprise, as both were expected to receive promotions in late August. But all indications suggest that theirs won't be the last heads to roll, as the current upheaval at the highest levels of the Tatmadaw continues.

Last week, more information leaked by military sources suggested that at least five generals—Maj-Gen Myint Soe, chief of BSO-1; Maj-Gen Kyaw Phyo, the inspector and auditor general; Maj-Gen Khin Zaw Oo, the adjutant general and chair of the military-run Union of Myanmar Economic Holdings Ltd; Brig-Gen Thein Tun Oo, commander of the Triangle RMC; and Brig-Gen Khin Maung Htay, commander of the Coastal RMC—are all under investigation.

Once again, the MAS has linked all five to corruption. However, military observers and businessmen in Rangoon are not buying this, and say they believe that it is just the latest sign of internal conflict in the Tatmadaw.

The Thailand-based Shan Herald Agency for News, which often covers Burmese military affairs, reported on July 27 that Myint Soe and other officers at the brigadier-general and colonel level had complained about worsening poverty among soldiers and their families.

“The Tatmadaw formed a welfare committee to assist troops and their family members after Gen Min Aung Hlaing took over as commander in chief, but unfortunately it hasn't been very successful,” said Bo Htet Min, a former battalion commander living in exile.

“Sadly, high-ranking military officials are getting richer, while ordinary soldiers are struggling to get by,” he added, suggesting that this has become an increasingly divisive issue in the Burmese military.

Even Min Aung Hlaing has begun to publicly acknowledge the need to address economic deprivation among rank-and-file soldiers. Speaking at conference held by Burma's War Veterans Organization on July 13, he said that the current government would strive to surpass the previous regime's record on poverty alleviation.

“In the time of the Tatmadaw government, concerted efforts were made for reducing the poverty rate from 32 percent to 26 percent by laying down five rural development tasks. The [current] government is striving to reach 16 percent poverty rate in 2014-15,” he said, according to the state-run newspaper, The New Light of Myanmar.

He added that an “increased pension salary” for war veterans and their families promised the previous month would come into effect in August.

Another issue facing the military since March 30 is the fact that the current Tatmadaw commanders are juniors of the former top generals who now occupy all of the major government leadership positions. This includes not only the president, vice president and house speaker, but also chief ministers of the states and regions.

For example, former BSO-5 chief ex Lt-Gen Myint Swe is the current chief minister of Rangoon Region; former BSO-1 chief ex Lt-Gen Tha Aye is chief minister of Sagaing Region; ex Lt-Gen Ye Myint, the former chief of the MAS, is the chief minister of Mandalay Region; and former BSO-4 chief ex Lt-Gen Khin Zaw is chief minister of Tenasserim Region.

This situation has created power and business struggles between current and former commanders. In mid-May, for instance, it was reported that Tha Aye, the Sagaing Region chief minister, complained that gold-mining licenses granted by the Northwest RMC, which includes Sagaing, were not in accord with the law, while Ye Myint, the chief minister of Mandalay Region, was engaged in a dispute with Brig-Gen Ye Aung of the Central RMC over granting vehicle licenses to businessmen.

The role of the BSO chiefs also overlaps with the responsibilities of state and regional chief ministers. According to Burmese military expert Maung Aung Myoe, the duties of the BSO chiefs include not just overseeing military operations in the RMCs, but also supervising state development projects and coordinating ministerial activities. Under the new power structure, chief ministers are now responsible for supervising state development projects and ministerial coordination.

Meanwhile, a number of BSO posts have been left vacant or are about to become vacant. BSO-6 hasn't had a commander since March, when Lt-Gen Soe Win was promoted to deputy commander-in-chief of the defense services, and the top spot at BSO-3 has been unoccupied since Maj-Gen Hla Min was appointed defense minister. Tin Ngwe's retirement means that BSO-5 also has no commander now, and with Myint Soe under investigation, BSO-1 is also likely to become leaderless in the near future.

That leaves just two BSO chiefs securely in command: Maj-Gen Aung Than Htut, chief of BSO-2, overseeing the Northeastern, Eastern and Triangle RMCs, and Maj-Gen Thet Naing Win, chief of BSO-4, overseeing the Southeastern and Coastal RMCs.

This situation has led to some speculation that the Tatmadaw may return to the days of having just two BSOs, as was the case from 1979 to 2002. The first BSO was formed under Brig-Gen Tun Ye in 1978, when government troops were battling with Communist insurgents northeastern Burma, and the second in 1979. The other four  BSOs were formed between 2002 and 2007.
