Two cases of illegal immigrants finding unusual methods of sneaking into countries have recently been in the news:
Case #1: U.S. border police found 13 illegal immigrants inside a fake Budweiser beer van.
Case #2: British authorities found four illegal immigrants hiding inside a 32-foot-tall fake Christmas tree in the back of a truck. The tree was made of aluminum and nylon, and had been ordered for a town center display.

Observations of an American Soldier During His Service With the A.E.F. in France" Edward Alva Trueblood (1919) and he was talking about an amoured observation tree he used.
I didn't really understand until I saw this article "WW1 Camouflage Tree debarked" http://www.abc.net.au/news/stories/2008/08/15/2336894.htm.
Perhaps the most interesting thing about it is how they would chop down a tree during the night and then replace it with one of these so that no-one would notice a "new" tree that just grew overnight.
