PzG Modern Q: Unarmored Weapon modifier

[armyduck95]

Gents, I post here because
1. - PzG Mod has a lot of potential 4th ed. rules and nuances, that might be similar or different than PZG
2. - I like keeps rules discussions in one part of the forum for easier reference. If I need to repost in PZG modern I will

Ok - my question.
1. Does an unarmored vehicle (i.e portee, or Jeep with 106mm recoiless rifle) receive the +1 Bombardment Shift for "unarmored weapon" like an AT Gun/Towed Arty unit?

My assumption = yes

Justification:
1. In PzG WII the +1 bombardment shift is specifically to account for the vulnerability of Towed Gun units
2. In PzG modern the same modifier exists but is changed to "unarmored weapon" which certainly accounts for towed gun units, but why would it not account for other "soft"/vulnerable unarmored units like Jeeps, portees, etc.?

Thoughts?
