It's just a terminology issue. "Cabin" is not a common defense term, whereas "shelter" is. There are many types and sizes of shelters. Take a look here for some examples: http://www.army-technology.com/contr...d/gallery.html

Another terminology issue (word nits) is fixed site vs transportable (can be moved from place to place) vs mobile (has its own inherrent means of being moved) vs fieldable/deployable (not too different from transportable/mobile but with a bit mroe of a tactical emphasis).
