Title says pretty much it.
To be more specific: How do you destroy this bastard WITHOUT the use of strategems (barrage, laser, rail canon strike etc.)?
Does he have any vulnerable parts on the back - like the other tanks - but they are not glowing?
How can I kill it with a auto cannon? I usually don’t carry the thermite granades.
Everyone who keeps saying shoot the vents, read the post again please. OP specified the Barrager tank, which has no vents.

OP, according to the wiki you can just shoot the top of it with Recoilless or any anti tank gun, and lacking that the rear of the body is medium armor.
Quoted from wiki: Unlike other Tank turrets, the Barrager’s MRL lacks a vent weak spot. However, the MRL itself is a large target susceptible to anti-tank weaponry such as the GR-8 Recoilless Rifle or G-123 Thermite. If a Helldiver lacks anti-tank weaponry, the rear of the Barrager’s hull can be damaged by medium armor-piercing weaponry like the AC-8 Autocannon.
That was (kind of correct) a few patches ago: there ARE vents behind it, on the chassis - when it first appeared shooting it would be almost completely useless, but now those weakspots destroy them just like the other tanks.
