4th Edition Rules - comment now or forever shut yer trap!

[rerathbun]

I'd also suggest we change the wording of the definition of AFV to differentiate Armored Transports from AFVs. As written, an AFV is "Any unit with a printed armor defense value (even a value of 0)." That was never changed from the first edition of the rules, despite the addition of (armored) prime movers in later games.

Perhaps
Armored Vehicle (AV) -- Any unit with a printed armor defense value (even a value of 0).
Armored Fighting Vehicle (AFV) -- Any Combat Unit with a printed armor defense value (even a value of 0).

[Note: in the Definitions Section, Combat Units are defined as "Units possessing a direct fire, bombardment fire or anti-tank fire value. Unarmed transports and leaders are not combat units."]

This would clarify which rules apply to which units, such as:
Units with direct-fire values only do not impede the movement of AVs (5.41)
Only trucks and AVs may be attacked with anti-tank fire. (11.0)
Regular leaders can activate Armored Transports and APCs, but cannot activate any other type of AFV. (6.83)
Cavalry and transports can’t dig in. AFVs can. (16.23)

(Changes to the rules in bold)

The Soviet KMS would still require a note that it is an exception to the rule, since it is Prime Mover (not an AFV) despite having a Direct Fire value.
