If you are making use of Tactics:Land (AToW, pg 156) and have a 'Mech with the Battle Computer or Command Mech quirks (both SO, pg 193), is the bonus added to the Tactics:Land bonus? I.e. everyone agrees to allow quirks and to use Tactics:Land and a MechWarrior with 2 tactics and a Battle Computer, has active communication with the rest of his lance, and is the lance's commander, do they receive a +4 initiative bonus?
Going further, what happens if MechWarrior Bob has the Battle Computer but Lt Jen has the Tactics:Land skill? Does MW Bob's Battle Computer help his commander at all?
