==Cipher #2==
This cipher is a Columnar transposition cipher with Pentagon and Classified keys for duplicates numbered backwards.
The plaintext is as follows:
"August 8th, 1947
I've been logging materials acquired from Group 935 for some days now (Major Sawyer has asked me to evaluate files pertaining to undead experimentation) and this afternoon I happened upon an old friend.
Hidden deep away in storage was Dr. Maxis' Original Matter Transference Prototype. Apparently, it was one of the items the Americans acquired when splitting Group 935's resources with the Russians. Unsurprisingly, it's in a terrible state of disrepair. Missing pieces, badly damaged, completely non-operational. To be fair, Maxis himself stopped using it after the failure of those initial tests in 1939.
While useless in its current state, it will provide great reference when we begin teleporter development at this facility. One thing I had never noticed before - scratched into the bottom of the machine was a message: "For M , who started me on this journey."
It struck me as odd… I can't recall anyone at Group 935 who went by that initial. I haven't the faintest idea who Maxis could have been referring to.

==Cipher #3==
This cipher is a using "CLASIFEDBGHJKNOPQRTUVWXYZ" as a key.
The plaintext is as follows:
"CLASSIFIED
11th July 1961
MEMORANDUM FOR SECRETARY OF DEFENSE
SUBJECT: DIVISION 9 ACQUISITION AND THE ELEMENTAL SHARD
I've had my men examine all materials acquired from Division 9 in 1946 and have been unable to find the elemental shard. According to our records it was on the original manifest for the formal acquisition of materials and verified as delivered. So I'm more than a little perplexed as to where it's ended up. I see two possibilities:
1) It was lost/destroyed in transit which seems highly unlikely given both it’s size and density
2) It was intentionally taken by a specified individual and is being kept from us. As to who might have taken it, I have my suspicions. For several years Groom Lake was our primary storage for all Division 9 materials.
Perhaps Pernell may have answers as to the fate of the elemental shard.

==Cipher #4==
This cipher is a with A=5 and B=25 as keys.
The plaintext is as follows:
"CLASSIFIED
2nd November 1963
MEMORANDUM FOR FILE
SUBJECT: HANFORD PROJECT INVOLVEMENT
Today the Hanford project has formally been integrated with the Broken Arrow Initiative
We’ve requested they immediately begin investigating weaponized solutions to "combat" the Samantha threat. Groom Lake is delivering a shipment of element 115 to the site in Washington so they may begin testing.
The Hanford project has requested access to all research regarding the MPD reconstruction project, however I declined this request.
At this time this project should remain at Groom lake – in recent months they have proven more than capable. It may be our greatest asset in the fight against this threat.

==Cipher #5==
This cipher is a Vigenère cipher using "Classified" as a key.
The plaintext is as follows:
(cough)
Field Report...
(heavy cough)
I don't know why I'm doing this.
Is anyone even receiving me?
(cough)
If you are, then all hope is lost. I'm the last one. The others...
they're... gone. We failed.
(cough)
I don't know if there are multiple outcomes, or if this has always been the only one. No matter what we do, what we fix, we still end up here... this time travel shit, multiverses, shit fries your brain.
(cough)
I hope Richtofen established contact with the others.
Woke them up. It's the only way now. It's up to them.
(cough)
Damn it's cold... very cold...
(beat)
Not much time left now.
