The modern equivalent of the old parachutist mechanism where you place a series of paper chits representing the paras onto a steel ruler, turn it over at a pre-determined height allowing them to float down, thereby simulating dispersion.
My first Wargaming oppo, Steven O'Leary used this against his younger brother. The game had his Germans against his brother's British.
The Brits defended a river which was crossed by an Airfix Pontoon Bridge. The attack stalled, so Steve (aka Oscar) unleashed his Fallschirmjäger
(All conversions as Airfix had yet to release theirs

) Squares of paper were duly cut up & dropped. Pandemonium! Paratroopers went everywhere!
Behind the other German troops, on the bridge, in the river and two VERY unlucky souls right in front of a British trench. Much fun.
