computing it, you determine that the corrections for this MET are R28, +70.
Compare this correction and determine MET corrections to apply to the initial RP Data.
SITUATION J: Several hours later, you receive a third MET and determine the
corrections to apply for this MET are R20, -20.
Compare this correction and determine MET corrections to apply to the initial RP Data.
SITUATION K: After computing the METs, the Platoon Leader instructs you to
update your Data Sheet.
Determine new RCFs and update your Data Sheet.
