Removed the following units :

- River Crossing Specialists (Now handled by the new tank river crossing unit/equipment)
- Urban Assault specialists/Sapper Company (Now handled by the new assault engineer company and kind of redundant with the shocktroops)
- Workshop Company (Now handled by the new armored maintenance company)

Rebalanced these units :

- Police Infantry : It was too effective/broken and effectively kills resistance too easily, needed to be more balanced but still maintaan an edge over normal infantry for garrison duties. Reduced its supression

- Fixed a small supply bug for AT gun companies
