Mum with whiskey welcoming soldier back home, US style (6)

I believe the answer is:

wigwam

'home us style' is the definition.
(type of Native American home)

I cannot understand how the remainder of the clue works.

(Other definitions for wigwam that I've seen before include "Native American lodge" , "Home for brave" , "Native American accommodation" , "Amerindian home" , "Reservation shelter" .)

I've seen this clue in The Guardian.
