Bv questions, been a long time

[Stallion12]

Does narc add any extra bv to the force when a mech with it is added? What about tag?

I know ci is as n extra 5%.

NARC and NARC tracking SRM/LRM ammo dont add any BV besides what the weapon costs.

Using TAG without Semi-Guided ammo doesnt add anything new either.
Semi-Guided ammo uses some weird math

[Col Toda]

The weird math being you multiply the bv of semi guided ammo by number of TAG units . You need 3 units with TAG to make it worthwhile so frequently that 1 ton of ammo cost 4x as much

It also gets added to the units with TAG before their Gunnery/Pilot modifications.

So, not really weird, just annoying to account for with planning software not handling it at all.
