RE: Motor Operated Valve. The head of the operator is often shown as M inside a square. The limit switches ZSC/ZSO is acceptable under ISA. I have never seen ZSH/ZSL (high and low for a linear valve I suspect) in my industry. If the valve is used for on/off, it usually takes a XV or UV tag name. If the valve is used for regulatory control application, then they would take the normal PV, FV, TV type of designation. I have also seen HV for operator control only valves.
As an Army infantryman, you'll need a combat score of 90, this score being determined by the sum of your ASVAB scores in arithmetic reasoning, coding speed, auto and shop information and mechanical comprehension.
Scoring on the APFT is based on gender, age category, number of repetitions performed of the push-up and sit-up, and run time. Score tables are found in Army FM 7-22 and on Department of the Army Form 705, Army Physical Fitness Test Scorecard. The score for each event ranges from 0 to 100 points; a minimum score of 60 in each event is required to pass the test. The soldier's overall score is the sum of the points from the three events.
