A 20-year-old member of the US Marines has been charged after assaulting a 60-year-old woman who works for the Australian Defence Force (ADF) at Gallipoli Barracks in Brisbane's north-west.

Police alleged the soldier attacked the woman while she was in her car in the Enoggera barracks carpark at 3.15pm on Tuesday.

Police said he also assaulted a police officer who tried to intervene in the altercation.

The woman was taken to hospital with non-life-threatening injuries and was later released.

The Marine was charged with serious assault of a person over 60, assaulting a police officer and wilful damage. Authorities have not revealed what the American soldier was doing at Gallipoli Barracks.

The US Marine Corps is facing a $25 million law suit for failing to discipline a colonel over his lewd conduct in Darwin which included sending inappropriate text messages to a female Australian major and showing pornography to a male navy commander.

The law suit was initiated last week by a woman whose child was sexually abused by Colonel Daniel Hunter Wilson after he was transferred to a new command in the US without being disciplined over his Darwin behaviour.

Australian military officers could be asked to give evidence in support of the legal action relating to Wilson, 56, who last year was sentenced to 5½ years’ jail for sexually abusing the woman’s six-year-old daughter.

Wilson, a 36-year veteran of the marines, was posted to Darwin for six months in the sensitive role as liaison officer for the Marine Rotational Force in early 2016.

But just 10 days into the job he was removed and sent back to the US following complaints about his behaviour from local officers, especially his Australian counterpart.

“Had they (the Marine Corps) handled it properly he would never have been stuck back where he could assault my daughter.’

A series of investigations into alleged sexual crimes committed by US marines in and around Darwin have been quietly dropped by Australian and American authorities.

That decision raises questions about whether Australia and the US are doing enough to investigate claims of sex crimes, and echoes decades of international concern about the cover-up of those crimes by US military personnel serving abroad.

ADFIS began an investigation into an allegation of inappropriate behaviour that stalled.

"All ADFIS action in this matter has ceased due to jurisdictional issues," the report stated.

... it was possible Australian and US forces were more concerned about the military relationship than they were about properly investigating the allegations: 'ADF are actively attempting to keep it out of the public eye'

Dozens of vehicles and apartment buildings affiliated with the US military in Japan were vandalized in Okinawa, shortly after a local man was killed in car crash blamed by authorities on a drunken American marine.

A total of 29 civilian vehicles owned by US personnel in Japan were covered with paint early on Monday in the towns of Ginowan and Chatan in Okinawa, Stars and Stripes, the official US military newspaper, reported.

The cars had the blue-colored English letter ‘Y’ painted on them by unidentified perpetrators, the paper said. The marking may be explained by the fact that ‘Y’ is usually added to the license plates of vehicles owned by those who are covered by the Status of Forces Agreement (SOFA), which provides a legal framework to the vast US military presence in Japan.

On Sunday, Japanese law enforcement detained Lance Cpl. Nicholas James-McLean over a fatal road accident. The US marine is said to have ignored a red light, crashing his two-ton military truck into a vehicle driven by a 61-year-old local man, who was later pronounced dead in hospital. According to the results of a breath test, James-McLean’s blood alcohol level was three times over the limit allowed in Japan.

A US service member has been arrested following a deadly vehicle crash on the Japanese island of Okinawa early Sunday morning.

Marine Pvt. First Class Nicholas James-McLean was driving a truck when it collided with another vehicle at 5:25 a.m. in Okinawa's capital of Naha, killing the 61-year-old driver, according to Jun Tamanaha from the Naha police department.

Police said James-McLean's blood alcohol content was three times the legal limit.

Okinawa residents have protested the US military presence on the southern Japanese island for years, in large part due to violent and fatal incidents involving members of the US military.

The case will be sent to the Naha prosecutor's office Tuesday morning, which will investigate and decide whether or not to indict James-McLean, Tamanaha said.

"It is extremely regrettable that this accident happened even though Japanese government has repeatedly asked for the thorough implementation of preventive measures and enforcement of disciplines," Japanese Chief Cabinet Secretary Yoshihide Suga said at a news conference.

Japan is demanding that the US military "enforce the strict discipline and take preventive steps and give a sincere response to the bereaved family."

US military personnel and civilian contractors working for American forces have been accused of multiple crimes in Okinawa this year. From January to October 2017, two have been arrested on allegations of robbery, two on allegations of rape and six on allegations of violent offenses, according to the Okinawa Prefecture Police website. Last year, US sailors in Japan were banned from drinking for an 11-day period after a petty officer was accused of driving on the wrong side of the road, hitting two cars and injuring two people, while under the influence of alcohol. In 2016, two incidents in the space of three months prompted widespread public anger -- in March, a US service member was arrested on suspicion of raping a Japanese tourist, and in May, a civilian contractor at a US base in Okinawa was arrested in connection with the death of a 20-year-old woman.
