Thousands of American and Filipino soldiers will on Monday kick off 10-day annual military excercises, according to Captain Alex Lim, a spokesman for the US forces, but there will be strict controls on their free time.
"There is a 10 pm curfew. The restrictions include no bars and clubs," he told AFP.
He also said that US soldiers will only be allowed to eat meals "in the vicinity of their place of dwelling," for example at their hotel.
US Marine Private First Class Joseph Scott Pemberton is now being tried for the crime in the Philippine city of Olongapo.
Activist groups have seized on the incident to attack the defence alliance between the United States and its former colony, staging frequent street protests against the presence of US forces.
However the Philippines, which has one of the weakest militaries in the region and which has a seething territorial dispute with China over parts of the South China Sea, has been seeking greater defence support from the United States in recent months.
