How does it distinguish friends from foe? Don't tell me something about recieving radio signals from UNSC neural interfaces because Moa and civilians don't have neural interfaces yet don't show up as enemies.

They probably recieve radio signals from UNSC neural interfaces.

DNA maybe? I have no idea how that would work, sorry.

FoF tags.

IIRC, friendlies (Marines, spartans, etc) should show up as green.

Covies (hostile FoF tags) are red.

Ones without have yellow.

It's why in First Strike (At least, original copy as I recall), when they landed on Reach the Spartans didn't show up as friendly, and just movement. Cause they disabled their FoF tags.

Still using a pump-action shotgun over 500 years in the future I see.

omg not realistic stop game production plz

Could use radar, but instead of showing an image of every object that the radio waves bounce off (back to the armour) to create a radar image, it could only show things that are causing different times for radio waves to bounce back to the Spartan's armour, which would be evidence for something moving, thus allowing the Motion Detector to only show objects which move and therefore cause differing "pingback" times for radar waves emitted from the MJOLNIR.

EDIT: And my theory would use elements of the FoF tags thing above my post.

Yeah thats when they return to reach they did it to confuse the enemy.

I think the Motion sensors work using radio waves to detect IFF tags / neural interfaces. It could use echodetection, IR waves, radar ect.. to locate movement.

Except how do you know that Covies have FoF tags?

  • 05.26.2012 3:00 PM PDT

What a waste....

UNSC personnel have IFF tags in their neural implants. Cortana says this while on High Charity in Halo 2.

Because they have a similar motion tracker in their hud?

And if they didn't have an FoF/IFF system, then the Spartans disabling theirs on Reach wouldn't confuse the Elites at all.

How about detecting the Flood(non combat forms) and Forerunner constructs?

It just picks up movement, it's just a highly advanced Sonar. It gets effected by weather and is not 100% reliable, as seen in The Fall Of Reach when Blue Team were in a Jungle with heavy rain.

Again, it detects movement...

And then assigns them as foe even though they don't carry IFF tags?

  • 05.27.2012 2:20 AM PDT

How about the forerunner constructs?
When sentinels are friendly they are green and when hostile they are shown red.

Perhaps radiowaves (or whatever radiation the Radar utilises) rebound off Covenant species differently due to their extraterrestrial nature? When this difference is detected,the dot becomes red. All other movement is displayed as yellow.

  • 05.27.2012 9:20 AM PDT

Not the flood...

Don't all UNSC personnel have some type of neural implant? I'd imagine that's how it works, and for someone like the Arbiter, it could be some kind of transmission he's giving off.

It's possible the system is programmed to recognise anything with a Covenant species' silhouette as a foe, while neural implants can make friendlies show up green. Anything else moving shows up as neutral/unknown.

Hanger one I just shredded with the SMGs until ammo was out and I just threw 'nades like a boss while BRing.

My experience playing Cairo Station on Legendary

Yes, it was was First Strike. The only way that John could tell it was them was the use of "Olly Olly Oxen Free!"

I like the sound of this theory.

This man, this man right here put it so eloquently that I actually cancelled my own 2000+ word long post.

The person who said participating is important, not winning, obviously never won anything.

I guess it works through a sort of sonar. In The Fall of Reach on Sigma Octanus, Chief says something about the radar being useless because of all the movement in the jungle. In the games it's just dumbed down to make it easier for gameplay.

But I guess it works with sonar and in conjunction with the FoF tags which would ping back if ally or not.
