Creeping barrage spam

[Beast Slayer]

Airborne 80 mm mortar called in by the observation squad have creeping barrage ( after vet 2 ) which cost no munitions and have insanely short cooldown which means I can activate it again right after the first barrage is done. This way I can spam this ability for free over and over again. I do not think that this is intentional or is it? Also this mortar cost 25 mun to produce. Why? Munition cost for mortars was removed in the recent patch and the caliber is same as the 80mm german version which cost no munitions. Is this an oversight?

AFAIK this is an oversight

Just want to add that american 60mm and german 80mm mortar have the same issue as airborne one. Their creeping barrage is also for free with very short cooldown.
