I've been ammo racked before by an arty in my E100
The view ports and the bar that connects them seems to be the only weak spot from the front. Lower front plate also works if you have a round with enough penetration
Never seen an e-100 get ammo-racked before.
i agree with Jerry - i aimed at angled lower glacial when he came round the corner on el halluf - no damageshould have gone for end wheels
You can deal damage when hitting the view port, however it is unlikely.
