That's a good way to start. Field artillery is easier to build and
doesn't require any fancy electronics, so you get on the field faster
and have fun sooner.
You'll want to start by locating an inexpensive, used paintball marker.
A simple mechanical trigger will suffice. Purchase a "door lock
actuator" to pull the mechanical trigger. You'll only need a simple
button to control the actuator, which pulls the trigger.
Then, build a frame to hold the marker and make it look like a howitzer
(if you stand back and squint). The upper part of the frame (that holds
the marker) should be separate from the lower part (that sits on the
ground) so that you can rotate the upper part.
Rotate and elevate can be done either mechanically or electrically. For
mechanical control, get a couple used brake cables for a bicycle and
configure them to move the marker up/down, left/right. Cheap,
inexpensive, reliable and easy to install.
For electrical control, a pair of slow turning motors are the easiest
solution (approx 4 RPM). You can attach an arm to the motors and move
the marker using push/pull rods. Or, you can attach a gear to the
motors and move the marker using another gear. Or, you can use a pully
on the motor and a move the marker using a belt. Or, you can use a
rubber wheel on the motor and move the marker using friction.
A pair of DPDT switches will provide FWD/REV control for both motors
without any additional electronics.
Once you've got the basic system working, you can start adding more
complex electronics (if you want) to get things like proportional
control and slower motions, but the basic mechanical/electrical systems
described above are definitely sufficient to have some fun shooting things.

I have been a long time creeper of the forums. I'm really interested
in building an Abrams as well but have very little knowledge on
electronics. Thought about getting my feet wet with an M777 howitzer.
Any suggestions where to start?
