Hello,
thank you for the report.
Unfortunately, I cannot locate the ladder you are talking about. Would it be possible to add a screenshot of a map or coordinates of the place?

Thank you very much.

added screens.

should of said strais control tower .D

Arma basic issue, as it contains no "drop yourself down a ladder until you can grab it, to climb the rest" animation. In order to fix that, they'd either have to create an advanced "ladder-boarding-mechanism" which requires probably a hilarious amount of effort for a little feature, or simply make fit ever ladder model to extend 1 man length above the ground (as we know it from jumping boards on swimming pools).
