I agree with Sheriff and VaTechRoomie from another thread that this Friday 30 Jan is the day . . .
Also agree with Iowa73 . . .
It appears scholarship winners have 30 days to respond via email or fax accepting the scholarship offer after they receive the Army's official letter. Since the next/final Army ROTC board this year begins on 9 March, the Army probably wants to hear from the 2nd board winners before the 3rd/final board starts so they know how many open scholarship slots they can allocate. By my count, Saturday 7 February is 30 days from the start of the 9 March board, so the official scholarship offer letters need to be delivered to each recipient by Friday 6 February. Mail takes 3 to 5 days so letters need to go out in the mail NLT Friday 30 Jan or Saturday 31 Jan to make this timeline -- provided of course that all of my assumptions are correct . . .
. . . Best of luck to all
