Vehicles with weapons on them

I remember before garry updated GMod 10 to GMod 11 ( A.K.A GMod updated to the orangebox engine ) there was vehicles with tau cannons on them in the small building on gm_construct, but now they aren’t there anymore so i’d like to ask, what is the command to spawn ANY vehicle with ANY weapon

Exemple : Jeep=Tau Cannon Boat=Helicopter Gun Jalopy=Ammo Radar

Actually it was GMod 9 >> GMod 10. GMod 10 is Garry’s Mod that is available on Steam.

But is there an ENT command that allows me to spawn those vehicles with special weapons/items on them?

We need weapons with vehicles on them.

So what’s the command?

Do you mean this?
