however so far I am not able to enter corps or army within a town, I guess it is normal.
Yes, this is my understanding, too. Although by reading Randomizer's reply, it sounds like it is possible to have a container unit enter a city. I haven't ever been able to do this, however. The only way I've ever been able to garrison a town is by removing brigades from a container and then dropping them into the town.
But how can I use forage instead of supply cost ? In emeror edition it is easy by turning each unit to forage but in FOF I have yet to understand how foraging ???
Then i guess when foraging I will no more have reinforcement ??
I still don't understand supply 100%, either, but I read in the manual that forage happens automagically, so you don't have to assign troops to forage. Apparently they will forage if it's available. From page 162 of the e-book manual:
Each province can also provide a certain level of Supply via forage. The Forage value of each province is included on its control box at the strategic level, and indicates the number of points of strategic supply available to brigades foraging here.
Supplies from foraging are first made available to units that are friendly to the controller of the province, then to any enemy units in the province. Forage supply is only distributed to brigades with fewer than 5 levels of strategic Supply. Forage is distributed to brigades in military groups with higher-rated Logistic Staffs before being distributed to groups with lower rated Logistic Staffs. A unit that receives forage receives 2 Supply, and uses 2 levels of the province’s available forage supply.
