I was just monitoring the shooting call at Jane & Lawrence which is the border for 12 and 31 Division. They had so many units from 12 Divsion show up that they actually patched 12 on to the 31 band and 11 division remained on the 11/12 band. This is the first time I have come across this and was very impressed with how fast and smooth it went. After 12 cleared they patched them back to 11/12 band. great listening!!!!
