US Marines and Australian veterans are looking forward to marching alongside each other when Darwin holds Anzac Day commemorations.

About 200 US Marines are stationed in Darwin for the dry season for training, and two platoons of Americans, about 90 people, are set to take part in Anzac Day proceedings on Thursday.

Marine Gunnery Sergeant Larry Thomas, 35, has been in Darwin for about three weeks and said he was looking forward to honouring Australian soldiers.

"I am going to the dawn service in Darwin and the parade there and then I will be trying to go to the Palmerston parade as well," Sgt Thomas said.

"I think it is a good bonding experience between us and the Australian army.

"It is not like our own Memorial Day event ... you do a lot more traditional things," he said.

In 2012 Marines marched in the Anzac parade in Darwin for the first time.

Australian Vietnam War veteran Peter Mansell, the NT coordinator of the Returned and Services League (RSL), said he supported US Marines taking part in Anzac Day.

"Last year while (RSL) president I invited the American Marine Corps to march with us," Mr Mansell said.

"They are brothers in arms. We have fought alongside American forces for a long time," he said

A dawn service will be held at Darwin's cenotaph on Thursday not far from where the American warship the USS Peary sank during the bombing of Darwin in 1942.
