Merkava 4M AAMG vs Infantry

[jivemi]

In a current campaign in 2018 the Merkava 4Ms do not fire their AAMGs against infantry, even with their cannons turned off or down to 4 Heat rounds. Is this normal? Thanks.

Update: Now one immobilized Merkava IS firing, least at close range (400 meters in this case). Funny 'cuz the unit info gives both CMG and AAMG the same range (2400 meters IIRC). [Edit: Then it stopped firing again, dunno why--hasn't taken any more casualties]. Also, looking at a previous save there was one tank that fired once (it was down to 89 firing opportunities out of 90). Weird, no?

(FWIW replaying several saves Merk AAMGs usually fire within 300 meters, rarely beyond. One may use the "W" key to fire either MG but as noted the CMG alone will consistently fire beyond 300 meters without it.)
