Cannot reinforce some units

[gocromwell]

I cannot reiforce some units even after placing them in a victory and city hex - any ideas why please?? Currently playing Stalingrad but has occurred in other scenarios

What does it say if you hover your cursor over the reinforce button?

[gocromwell]

It says Unavailable Equipment pool for this type is empty. I tried deleting on unit & that gave me a bit to reinforce another. Assume I need to figure out how to put some units into reserve to enable me to reinforce others?

[Folklore]

I think that should concern only captured vehicles. Maybe you're using some kind of commander trait that limits the reinforcement?

[bendtheknee]

you are playing with "industrial connection"
the tiger1 for this battle (stalingrad) is a prototype, you have simply exhausted the number of prototypes available, as probably for your other fights

Looks like you maybe right 2 of the units were Tigers & the other two were Panzer IIIL
