Disconnect battery to avoid some part sucks it to dead. Leave it with a full
tank of gas. If the last oil chance is longer time ago make oil chance
before you sat it down.

Two months is not long for vehicle storage.  Don't worry about it.
As others have said, disconnect the battery negative.
Write down the radio code first though.

I once left a car for two months and I would have welcomed a rusty gas
tank and dead battery to what happened to the car. High humidity rotted
most of the flooring out as well as the rocker panels. When I went to
dust it off I found mostly paint along the bottom and very rust metal
underneath.
So, store it in a warm dry place.
If you can find someone you trust, have them start it up once a week
and move it back and forth.
Modern gasoline is not pure gasoline anymore and a lot of it will turn
to syrup and separate into solids. This can plug up the fuel system,
nasty. Your gas tank shouldn't rust as modern cars have a closed fuel
system with an air line runing back to the tank from the engine area.
Make sure the gas cap is on tight.
. . . anyway, my 'two cents.'

Two months isn't too long.  There's no reason to pack everything in Cosmoline.
Just put some fuel stabilizer in the tank, drive it around a little bit, then
disconnect the battery, put a car cover over top or put it in the garage, and
go on.

Some folks might recommend pulling the plugs and squirting a little WD-40
in each cylinder to keep condensation from causing rust problems.  I think
that's probably overkill for a couple months.  On the other hand, given the
current situation, you could wind up on extended deployment for a while...

two months?  Disconnect the battery so it's not sucked dead by the radio
& computer, fill it with gas and air up the tires so they don't go flat.

Maybe throw some fuel stabilizer in there, but two months isn't that long.

As others have said.  8 weeks is nothing.  Disconnect the battery is about
it and I doubt that is requird.  I have a boat with Chevy 350 and winter
storage prep is fill tank and pull battery.  Never had an issue.  The boat
is a 1992 so if I've shortened it's life, not sure how much.  I do usually
put fuel stablizer in but haven't always.  I have heard the new fuel blends
are "no good after 2 weeks" which doesn't pass the common sense test for me.
A modern car getting 30+ MPG driven to the grocery store once a week will
last several weeks between fillups.

Two months is no big deal.  If possible treat the car to an oil change
beforehand.  Try to store the car in a cool or shaded location and
disconnect the battery.  Since you are in the military and your stay
could conceivably be extended or shifted to another location you might
think about a backup plan for prepping the car for more permanent
storage should the need arise.
