If you google it you would find this...
You are given these in order, so if you pass the first, you won't take the second, etc. Passing the first or second test will flag you as normal color vision, and will not restrict you from any MOS. The PIP is very difficult to pass if you have any degree of color deficiency. Even some without a deficiency fail. The FALANT is meant to catch those who fall through the PIP cracks. It is meant to pass individuals with mild color deficiency. If you pass the third, you are flagged as R/G. If you fail all, you are a non-color vision applicant.
Note: It seems that many applicants are being told failing the PIP means they're deficient even if the pass the FALANT. This shouldn't be the case, as the whole point of the FALANT is to be an alternative to the PIP. For the other branches, if you fail the PIP, the FALANT is used in this way since they don't have the vivid R/G test. Apparently the FALANT is pointless when it comes to the Army.
Based on this, you will either have every MOS to choose from (passing PIP/FALANT), a list of less than 50 (passing vivid r/g), or only a few (failing all).
Failing all three tests (no color vision) restricts you to the following: 15P, 27D, 36B, 42A, 42R, 42S, 56M, 68G, 68H, 68W, 68X, 88T, 92M, 92S. MOS 38B, 79R, and 79S are also available, but are not entry-level MOS.
Passing the vivid r/g, in addition to the above, opens up the following: 11X, 12D, 12N, 12V, 13B, 13C, 13D, 13E, 13M, 13P, 18X, 31B, 31E, 31K, 68Y, 88H, 88M.
There are additional MOS that may be available for R/G applicants with an ETP (exception to policy): 12C, 35N, 35S, 89B, 92A, 92G.
Lastly, the following may be available to non-color vision applicants with an ETP: 12W, 31B, 31E, 88M, 92Y.
