Speculation on some of the Forerunner Arsena

In this image right here, we can see blue shields in the distance, which would give to mind Jackals. But, most Covenant artillery originated from Forerunner artillery.
Discuss amongst yourselves.

So Forerunners also have energy shields, case closed… lol.

Despite Forerunner heritage having inspired covenant technology, the design and architecture of the covenant was clearly not inspired; i believe these are jackals.

Covenant arsenal=forerunner arsenal w/different looks…
But if forerunners are an enemy or whatever i am sure they will have a bunch of new crazy weapons/vehicles.
Who remembers the forerunner tank that was supposed to be in halo 2?? That sounded epic.
DO IT 343i. DO IT.
