The nation is holding an election in a electoral process broadly rejected as a farce, with major political parties banned, numerous figures jailed and as much as half of the country unable to participate because of an ongoing internal conflict.
The military government is conducting a phased ballot nearly five years after it took control in a takeover, which sparked massive protests and escalated into a devastating conflict.
Analysts note the military regime, with backing from Beijing, is attempting to validate and entrench its power as it seeks a way out of the costly stalemate.
"There are no conditions for the practice of the rights of freedom of expression, assembly or peaceful assembly," the United Nations' top human rights official Volker Türk stated.
More than 200 people have been prosecuted for interfering with or criticising the polls under a new law which carries severe punishments, including the death penalty.
Director Mike Tee, performer Kyaw Win Htut and comedian Ohn Daing were among the prominent figures convicted under the law, which was passed in July. They were each handed a prison sentence of seven years after speaking out against a film endorsing the elections.
Civilians are "facing pressure from all sides," Mr Türk noted in a comment, adding that armed rebel groups have issued their own threats asking people to shun the polls.
The military has been fighting on several fronts, against both armed resistance groups who oppose the coup, as well as ethnic armies which have their own militias. It lost control of large parts of the country in a string of defeats, but regained territory this year following relentless airstrikes enabled by support from China and Russia.
All of this and the fact that large parts of the country are still under rebel administration presents a massive logistical challenge for holding an election.
Voting is set to take place in three phases over the coming weeks in two hundred and seventy-four of the country's three hundred and thirty townships, with the rest deemed not secure enough. Outcomes are expected around the end of January.
There is unlikely to be any voting in as much as one half of the country. Even in the townships that are voting, not all constituencies will go to the polls, making it difficult to predict a possible turnout.
A handful of parties, including the junta-supported Union Solidarity and Development Party, are fielding candidates nationwide, while another 51 parties and non-aligned contenders will contest only at the local levels.
Some 40 parties, including Aung San Suu Kyi's National League of Democracy, which scored landslide victories in 2015 and 2020, have been dissolved. Suu Kyi and many of the party's senior figures have been imprisoned under charges widely condemned as politically motivated, while others are in exile.
"Through dividing the vote into stages, the authorities can change their approach if the outcomes in the first phase do not go their way," noted Htin Kyaw Aye, a spokesman of the election-monitoring group Spring Sprouts.
Western governments, including the UK and the EU legislature, have dismissed the vote as a sham, while neighbouring group Asean has called for negotiations to precede any election.
The Myanmar regime has rejected criticism of the polls, maintaining that it aims to "restore a multi-party democratic system".
"The election is being held for Myanmar. It is being held for the citizens of Myanmar. It is not being held for the outside world," a military representative stated at a briefing last week.
Military leader Min Aung Hlaing cautioned earlier this week that those who choose not to participate are rejecting "progress toward democracy".
