Are there any Axis or Soviet units that DON'T reconstitute?
Similar to FiTE, some do, some don't. You can check the 'D21 Background' document for some general guidelines. You can look in the Editor to see which ones do and which don't. You can also run a Scenario Dump to check for a units Recostitution eligibility (hit 'Ctrl' and 'f', type in the unit name). I place my vote to add this info to the Unit Report dialogue box in some future version of TOAW, so it can be easily found. Maybe some don't want it to be known, though.
Overall, it's best not to lose any Axis units, and to destroy every Soviet unit you can, especially when they are unsupplied. [:D]
