Supply via Uboat

[Meteor2]

In a YT-Video the player used uboats to reinforce corps (!), that were isolated on coast hexes.
A sub icon is around 15 subs. If one sub is able to deliver 50t of supply, then that means 700t.
These have to be shipped without a harbour (!) to the coast. Since a Corps means 20000 men, every man will get 2kg per day (2 week turns).
Do you think, this picture is ok, to improve moral or hinder starvation of the unit?
Should uboats be able to supply Corps-seized units?

It can be a Japanese army or a division too. I don't think there is a control on the size of the unit being supplied.

My question was more in the direction, whether it should be possible, the uboats supply land units. Divisions maybe, but corps?
20000 to 30000 men! Probably not.

Interesting. I didn't realize subs could deliver supply's. The Japanese did use submarines to supply Army units on Guadalcanal. But as I recall it wasn't particularly effective. And as you have noted -- in the case of Guadalcanal the tonnage of supply delivered was pretty insignificant.

Also of Note -- In-game Motor Torpedo boat units seem to be effective at this task. The Japanese did a lot of resupply during the Solomon Islands Campaign via small barges and such (see JFKs book PT109). I assume that's "maybe" what's being replicated with Motor Torpedo Boats resupply capability? Although in game you can resupply a unit on Okinawa from a motor torpedo boat stationed at Saipan or Guam. Which maybe seems kinda "gamey".
