Thank you for your comments.
Apart from him maybe losing his ID card ,, I think it can do no harm to take it with him,any military discount into places will be gratefully accepted, .
Ii know he is very proud of his achievements so far in being a soldier.

So far we plan to visit , ground zero, a helicopter ride, Central Park , American football march, sttatton island, a broadway show ,whatever is on, Empire State Building, and whatever else we can fit in 6 days...so any discount offered even just for him would be super and make him feel appreciated..

As I spend all my spare time reading thr BA forum and enjoying especially peeps reports, I make a solemn promise to write a trip report on our return,
Thanks guys
