Vehicles in close combat without a melee weapon?

[Wassa]

Looking at some vehicles, they have a number of attacks, but there is no "weapon" for hits or damage.

 

I assume they they're both 1?

Every model has by default a CCW which has the profile of S(User) AP0 D1.

So a Leman Russ in melee will have 3/1d3/1 attacks with S7 AP0 D1 hitting on 6+ for example.

Basically, just think of the vehicle itself as a weapon.
