Propose that the A.I. machinegunners fire at OPFOR troops consecutively from one end of their group to the other and back again while on extended bursts. Note that they do not necessarily need to begin at the left or right end of the group and end and the opposite end. They may start at the most threatening of the group and then swing right or left, for example.
When fired at in the manner, the targeted group should react as if they are suppressed if they are A.I. {F18706}
