VBH = Verbindungs- und Beobachtungshubschrauber (german)
..."just" a Bo-105 without any weapons systems for light transport, training, VFR recon, liaison aircraft...maybe insertion of special troops (KSK)...no special recon systems. Like a civilian 105CB (with upgraded gearbox, tailrotor?)
Some PAH were downgraded to VBH, after the original build 105M (VBH) were discharged...
...I think....right?
