In a series of BBC interviews, soldiers in garrison towns have said their rations have been cut for weeks.
They say commanders have barred access to money they have saved, which is kept in a central fund.
Their action comes just over a month before Burma's first general election for 20 years.
Ahead of the 7 November polls, the BBC Burmese service has interviewed individual soldiers in garrison towns across the country.
It has built up a picture of deep resentment in parts of the army just weeks before the election, BBC World Service Asia-Pacific editor Viv Marsh reports.
Soldiers say their food-rations have dropped and that while prices have been rising, their commanders have blocked access to their savings.
"The rations have been cut to one-third of the usual amount. Our salaries are not enough to support our families," said one private from the Light Infantry Division No 701, based about 40km (24m) from Rangoon.
