OMG's repair rates are reduced significantly from regular Company of Heroes. This stresses using units thoughtfully rather than rashly. These following units can repair at the listed rate:
Repair Stacking
Multiple squads repairing the same vehicle will apply a .9 modifier to each surrounding squad. At a certain point the "Union Effect" kicks in which makes it less efficient to have more than a certain number of squads repairing. Keep in mind that while the repair rate is effected by the .9 modifier, the wear & tear remains the same for every squad. As a result, the Luftwaffe Squad looks like this:
