Some questions on modern flak vest,plates and helmets

[marentius]

Hi everybody,

I'd like to get some informations on the following subjects:

 

What kind of plates are worn in conjunction with the Air warrior flak vest system?The same SAPI plates worn with the OITV?

What is the biggest difference between SAPI plates and ESAPI?Are the new plates replacing the old ones?

has the distribution of the new EOITV already begun?

I see on sale on EBAY MICH helmet made by MSA or SDS (the warrior model,a little smaller than the normal MSA).Question is:following which criteria are the two different types of helmets distributed to the troops?Just by chance a soldier can get a MSA instead of a SDS or have these two helmets specific destination?

What about the so called "SEAL" or Special forces helmet (I mean the MICH helmet with chinstrap,pad system and cut away sides)?Is it produced on a regular basis?

Is the HGU 56 P still the only general helmet used by helicopter crewmen?

Thank you very much for all kind of informations anybody could provide!
