I'm playing the full campaign as the Axis on Normal difficulty, with no other options turned on.

When I want to reinforce air units, I'm given the option to reinforce them way past beyond strength 10, up to 100! All other land units of course hit the reinforcement ceiling at far lower values, infantry around 11-13, armour units around 20-25.

Are airplanes supposed to be reinforced that high or is it just a bug? I read through the manual but there is nothing in there about this.

Also, can someone tell me how to deploy paratroopers? Are they land based only or can they actually jump behind enemy lines?
