13.14 failed MCs in OP fire stop units

[cjsiam]

Combat Units: Units possessing a direct fire, bombardment fire or anti-tank fire value. Unarmed transports and leaders are not combat units. 

Leaders: Individuals who activate and direct other units. Each leader piece has two sides, each of which represents a different leader. Each leader's rank, morale, combat bonus and morale bonus are on his playing piece. See 6.0 for leader specifics including movement allowance.

2.1 Playing PiecesMost of the playing pieces represent military units that took part in actions covered by the game series. Others are markers which represent fortifications, smoke and minefields, indicate morale status, or show that units have moved or fired this turn.

The 3rd edition of the rules stated:
Personnel Unit: Motorcycles, mortars, anti-tank rifles (ATRs), and all units which are not vehicles, weapons or leaders are Personnel Units. Examples include (but are not limited to) INF, MAR, PARA, CAV and ENG.

Are leaders units? This question is not specifically addressed in the 3rd and 4th editions of the rules.

Rewriting the rules to clearly indicate how rules specific non-marker chits - units (however that is defined), combat units, leaders, transport units, transport units that are not combat units, vehicles, AFVs, etc - will take some serious effort.

I don't think a rules rewrite is necessary---I think a "clarifying addenda" could do it....what are the circumstances where this might be an issue, and how to handle each.
Moving
Stacking
Assaulting
Rolling for Fire Results

how are Combat Units, Leaders, Transports handled in each situation (and others)....4th edition....

I very often see questions about "units" and we need to put this to bed in an agreed way.....

One thing I learned while writing the Land Cruisers and River Fleets rules is how difficult it is to write rules that are complete while avoiding contradictions.

If a leader and a unit are running in the open, and are hit by OP fire....if EITHER unit fails MC (disrupt or dem) IT is halted...it has no impact on the other "unit" in the hex.
The leader failing does not stop the combat unit...and the combat unit failing does not necessarily stop the leader.....he could continue on if he choose...

Thank you for your reply. Yes, this makes sense. It is equivalent to saying that rules 13.14 extends to leaders, which, by the way, was exactly my preference (see my first post).

Human beings are fallible. The wisest among them recognize it and welcome errata.
