I have read through the forums to try to understand what the "V" ratings refer to and how they will relate to me but it is hard to try to find a solid answer so I just wanted to ask about my specific case. Hopefully someone can shed some light on this for me. My unfit memo has me unfit for chronic shin splints, V1-yes, V3-yes and V4-no. What started it all was when a M3A3 bradley 25MM cannon (the lower receiver, about 120 lbs) was dropped on my leg. It wasnt downrage but in the field when it happened. Any idea what those mean in realtion to my specific case? Would severance be taxed in this case? I have no idea what to expect for anything so any info would help. Thanks.
