Well since many of these will be fired from ambush, the soldiers will be carrying what they think they need and, presumably, will always take ATGM in the hope that a T 72 crosses their path: if it then turns out to be a truck with a squad inside, they might well use the ATGM if there aren't enough of them with automatic weapons;
Having seen one video where soldiers promptly dismounted from an APC and organized a defense after a tank was taken out, it may be wiser to target APCs before tanks. The tank crew may then decide to abandon the tank which can then be added to the UKR inventory.
RF senior officer losses seem to have abated, perhaps because they are pulling back and regrouping.
Hopefully UKR will be well supplied wherever RF makes its next push.
