Well, you can Play the Scenarios straight away IMO.
I even have a Skirmish Campaign Rule Translation to ViDe stats you can use:
Training
T1+ = Dedicated, Nerves of Steel, Tenacity
T1 = Dedicated, Nerves of Steel
T2 = Dedicated
T3 = -
T4 = -
T5 = Untrained
Morale
A+ = Ld 7, Nerves of Steel
A = Ld 6
B = Ld 5
C = Ld 4
D = Ld 3
E = Ld 3, Untrained
Leadership
Ld is factored in the Morale values.
Notes
Platoon Leader gain the Command Ability
If an Ability applies more than one time, ignore the second ability.
So a T1 A+ unit leader is at Ld7 with the Dedicated, Nerves of Steel abilities.
