+5% to range at vet 1 for ISG seems like the most meh veterancy of all time. I would rather see Hollow-shells return, but make it a timed ability. This way the player could activate hollow-shells for say, 10-20 seconds, and right click on a vehicle instead of having to barrage one specific spot on the map.
You could argue that it's miles better than:
Medkits, Infantry detection, counterbarrage or Sexton coordinated barrage (on the Valentine lol)
