One of the most irritating small things about the CMx1 command delays was that if you had a line of AFV's, HT's, trucks, whatever, you can bet that some were normal, some were green, some were vet, etc., and it really made a mess of the give the second vehicle a 5 sec delay, 3rd a 10 sec delay and so on, since different experience levels had different inherent delays.
It made for some serious micromanagement to get down a road.
