The PPS has undertaken reviews into decisions not to take action against 15 of the 18 soldiers reported to them by the PSNI.
Last year, it decided only one former British soldier – Soldier F – would face court.
Although Soldier F he has been charged, he has yet to appear in court.
Thirteen people were killed and 15 were wounded when the Army opened fire on civil rights demonstrators in Derry in January 1972.
A 14th person later died of their injuries.
The reviews were requested by the families of some of the victims.
The cases have been examined afresh by a different prosecutor within the PPS than the one who made the original decisions in March 2019.
The outcomes will be made public later today.
No new evidence was submitted for the reviews and solicitors for the families sent detailed submissions to the PPS setting out why they believed the decisions were wrong.
They believe about 10 other soldiers should be facing prosecution for murder and attempted murder.
They also argue Soldier F, as he was known at the Bloody Sunday public inquiry, should be facing more charges.
He is to stand trial accused of murdering James Wray and William McKinney in Derry in 1972 and is further charged with five counts of attempted murder.
The fifth relates to persons unknown.
At the time it reached its first decisions, the PPS said the available evidence was insufficient to provide a reasonable prospect of convictions for the other soldiers involved.
The families hope this fresh review will lead to more British soldiers being charged.
