3rd vs 4th edition

Also, some people have used modifiers for masked AT fire permitting, IIRC, an AT gun to be efficient (fire twice in a turn) and "hidden" unable to be spotted unless adjacent for its first fire of a scenario.  I could see doing something similar with any prepared position.  If nothing else it would demand a certain amount of caution on the part of the maneuvering force.

       Will try out what you recommended and report back in as soon as able.  I am in the process of PCSing (Primary Change of Station - i.e. moving) to a new duty station stateside.  My last job prevented me from playing anything at all.  I have been nothing but busy since Mr. Putin invaded Crimea.  I was the first lead planner for Atlantic Resolve, and was subsequently the Plans Branch Chief for US Army Europe (USAREUR). My next job, an XO for the Professor of Military Science at Virginia Tech, will be closer to a 9 to 5 (not counting Physical Training, which should allow some gaming time again. 
       I may replay "Bicycle races" from White Eagles or some similar river crossing scenario, and will report results. Only one question -  IIRC?  I never saw that acronym before.
