Help IDing a ration?

[Cortexmelon]

So I purchased this ration, looks like an old Russian or Ukrainian one, but it has 4 slots in it, while any images of older Ukrainian or Russian rations show only 3 slots.
Has anybody seen this one before, any help would be appreciated!

Found these photos of a ukraine ration and russian ration that look similar from the 2000's, but its still not all the way similar:

The plastic container looks like old Russian rations I have seen them but with different contents

Dont know if it helps but the "npn" marking is on the current FSB/FSO 24hr rations. Russian Federal Protective Service

Old school Russian IRP. The “ИРП” on the box is an abreviation for Индивидуальный Рацион Питания. Which translates from Russian as Individual Meal Ration.

Thanks for the help, appreciate it! I don't get why this thing is so hard to find any info or pictures of the time frame for it, it's strange.

Got it in the mail last night, and wow. This thing is an absolute unit! Biggest ration I've had yet, by far.

Hope its yummy . Since it seems rare let us know how it goes, unless this is more of a collectible for you.
