Turret Armor ratings for Pintle mounts

[Koh]

Could be because a 0 armor rating on a pintle mounted weapon would allow an otherwise armored vehicle to be destroyed by, say, assault rifle fire. The HMMWVs with a pintle mounted weapon that have 0 rating on their turret also have 0 all around armor. There are many HMMWVs in the US OB that have 1 all around hull rating, and these vehicles also have 1 as their turret all around rating.
