Research Development and Production

Research and Development is how your side gains access to more advanced equipment. There are 4 Tiers of units, Tier 0 to Tier 3. Tier 0 equipment is available at the begining of the campaign, with the more advanced equipment from the following tiers being introduced as the campaign progresses.

Production is how your side replaces equipment lost on the battlefield. Once you spawn a tank, aeroplane or other vehicle your side's factories immediatly start to produce another. This takes a number of hours, though if you aren't killed and manage to return to base (RTB) your piece of equipment will immediatly go back into the supply of equipment and the production will be cancelled. Production can be slowed down dramatically by boming enemy factories.
