If I understand your question...
The order you add force vectors is irrelevant. You should get the same resultant.

if the vector added in different orders then the resultent force is affected, because
the required field is a vector field with infinite range. The need for infinite field implies the field quantum must be massless. These are properties of and electromagnetic field, whose quantum is the photon. Therefore by requiring the local gauge invariance of electron field, existence of electromagnetic field can be inferred. Apart from the electromagnetic force and gravitational force there are two other forces - the strong and the weak forces. The strong forces are the ones responsible for holding the nucleus together. The weak forces cannot be categorized as being attractive or repulsive like the other three forces. They change one particle into another. For quantumelectrodynamics, the two fields required in the theory, electron and photon, where already
known at the time it was being developed. But, the situation was very different for the strong and the weak interaction. It took a long time before the strong and the weak forces could start making sense. The reason was that the necessary local gauge theory was not understood. The development of these gauge theories required introduction of new particles and force, which conformed to the necessary gauge symmetry and also made the theories sensible in terms of making them finite

If I understood your question correctly A + B = B + A and A - B = - B + A
So, the order of vector addition is not important. Resultant of two or more vectors depends on the magnitude and direction of the different vectors.

No
will a bullet strike a different spot when gravity and wind are figured in different order? no a vector must be changed to change the final result.

A vector has direction and magnitude. As long as you keep the vectors (including sign, which is the direction) as they were the commutative law applies, so a(vector)+b(vector)=b(vector)+a(vector).

Addition of vectors is commutative.
A+B = B+A
So feel free to pick whatever order seems best to you.

the order of addition doesn't matter at all
its just like adding two numbers...
