Question on Reinforcements

[ComradeP]

0% arrival chance reinforcements might be "tied" to a specific reinforcement with the same arrival time.

It makes sure those units will never arrive in a piecemeal manner (which they might with arrival chance set for individual reinforcements) but all at once. The units are not all grouped in one package because it's not possible to set different arrival hexes for units included in one entry in the reinforcements dialog.

Daily means an arrival check is done at the each game day, instead of each turn.
