Optional rules for armor enhancement

[Blackcloud6]

How many of you use the Efficient Move and Fire & Extended Assault optional rules?  They seem that they would give armor more punch in this primarily infantry game and give more realism to armor's mobility and shock power.  Do these rules upset scenario balance much?

On the surface they seem like no-brainers to me, but I have yet to use them.

I have used extended assault, to pretty good effect.

In my limited experience, extended assault favors the attacker because:
1. They allow for a slightly faster tempo (AFVs and APCs can assault a static defensive position in one turn instead of having to move adjacent to it one turn and assault it the next).
2. APCs are far more resilient to small arms opportunity fire than leg units. Sending a wave of APCs to assault a town and then sending the leg units can be an excellent tactic. Based upon my reading of "Dunkirk: Retreat to Victory" by Julian Thompson, I am leaning towards the tactic making sense (for the British).

Extended assaults make for interesting situations, especially if there is a limited of APC.

My only experience with Efficient Move and Fire was with Sword of Israel, not enough to have an opinion.
