i think the guns at utah would be a cool one....its probably the most famous one cuz winters got a promotion after that raid, and it was very vital for the boys on the beach!
other cool ones would be:
the guy (forgot his name) who runs alone past the 88s in bastogne...you could have the germans confused just looking at him....and him just running past.
a bunch of guys hiding under a fallen tree in bastogne
the raid on carentan
the one where shifty takes out that gunner in carentan
two guys standing at the window where a machine gun is shooting and holding a grenade ready to throw it in
if u feel like makin a dio with aircraft, make a bunch of small scale DCs and mount them on stands with guys jumping out, have tracers flying everywhere
a bunch of guys straped to parachutes trying to get free once on the ground
AND my favorite its not from Band of Bros but it happened in holland, its from a book from a series, the book is called The road to Arnhem by Donald R Burgett ( i highly recomend it, one of the best books ive read):
a guy was ambushed by germans, started screaming firing his gun, dives for cover under a german tank...(yikes) notices he used all his grenades...but finds an apple in his pocket, quick GI thinking, runs out (with his teeth) pulls the stem of the apple, runs screaming at the germans, throws the apple at them and the germans run for cover and he gets away from it... THAT WOULD BE AWESOME TO DO A DIO OF!!!
