Now that you are fixing bugs and balancing the game and can ask this.
Please fix the display of the model requirements to recrew weapons. It says 2, but ends up using 3 models, and in the case of the ostheer that means loosing entire veted squads by a mistake caused by the display of wrong information, a bug, or wrongly implemented changes.
This may be quite counter intuitive but the value displayed there is the minimal number of models needed to man the weapon. So if you have a squad with less members than this number you can't man the weapon at all, loosing the squad or not. Also, if your wapon is manned, but the number of models manning it drops below this number, the rest of them will run to the edge of the map (usually, sometimes the number of members to run is smaller f.e. in maxim or mg42).
The number you are talking about is the maximal number of models taken from squad when manning the weapon and it is
always 3. For all weapons. No need to display it at all.
So in fact this indicator is batter to show the number it shows as it gives at least some insight, even though the number should be shown somewhere else, than to always show the same number.
Mind that this is not true for abandoned vehicles as for them max value differs from one to another. Vehicles can be manned only with a set number of squad members, so the maximal value is always equal to minimal value shown on the indicator. So in this case exactly the number of models shown on this indicator will be taken from the squad. This can also be a reason of you misunderstanding what it means.
I hope it was helpful, ask if you have any questions about it
