Earlier on Wednesday, the DUP's Sir Jeffrey Donaldson said the UK government should consider introducing a law protecting soldiers in wars from prosecution.
The MP said a statute of limitations "not just focused on Northern Ireland" should be considered for the armed forces.
He added that this conflicts such as those in Iraq and Afghanistan should also be covered.
He added, that without a wider policy in place, there could be pressure for an IRA amnesty in Northern Ireland, which he said would be "totally unacceptable".
No 'amnesty' in NIO legacy document
New police unit to investigate past
The DUP is currently supporting the Conservatives in government through a confidence and supply agreement which was struck after the general election in 2017.
Lagan Valley MP Sir Jeffrey said that "a statute of limitations is a much broader issue," adding that his party believes "it should be dealt with separately from the legacy proposals".
"If you introduce a statute of limitations which relates only to Northern Ireland and our troubled past, organisations like the IRA would then press for an amnesty for their members and we believe it would be completely unacceptable to equate members of the armed forces with members of an illegal terrorist organisation," he said.
He added: "The law, not just UK law but international law, does not treat them in the same way as state forces and I don't think we should.
"We are not saying there should be an amnesty - we are saying that a statute of limitations should kick in after a number of years have lapsed in the case of our armed forces."
