Common house rules?

[Grumbler]

There is a common misperception regarding just what a "Meeting Engegement" is. The US doesn't even officially use the term, AFAIK. The US term is "movement to contact", which is what most europen armies would consider a reconnaissance in force. IN WW2 most M/E's happened when the line of battle was broken, and one side was moving up reinforcements to restore the line and the other was trying to exploit the breach.
Ths Soviets saw a Meeting Engagement happening as a result of a breakout and persuit force bumping into the enemie's reserves. That theory was never tested, since no Soviet style army was ever able to achieve a breakout. Although nobody really knows what happened in the Sino-Indian border battles of '62. The Indians achieved a breakout in '71 against the Paki's, but It's debateable if they were using Soviet tactics or just a lot of Soviet type equipment. Anyway, the Paki's fled, which means there were no reserves to create a M/E.
Anyway, the SP idea that you have Brigade or even Battalion sized formations wander around loose is ludicrous. The closest I can think of would be the Eritrean-Ethopian war of 5-98 to 6-00. I think the war was brought to a halt because the Eritreans broke loose an Armored Brigade and the Ethopians had nothing left to counter it with which made negoiations seem like a good idea.
That armored brigade was part of an infantry division, so they could hardly be considered to have been operating in a vacumn.
No politican will allow a 1-star general to just drive off with a few thousand men and a couple of hundred armored vehicles. Not to mention what the 2 star thinks about that.
