Nemesis By Chalicea ( Crossword Centre )

[Matakari]

Good afternoon, I’ve been enjoying “Nemesis”, a very smart puzzle by Chalicea. Have got lots of answers, but some clues I’m not sure of and would appreciate HINTS for the following, please. Thanks in advance!

www.crossword.org.uk/nemesis.html

A rather cocky little fellow who appears in the first row of the grid speaks the words that circle the remainder of the perimeter. He tempts a number of characters who appear as entries in the grid. Solvers must highlight his nemesis.

ACROSS:
12 In Reunion, white ordinary soldier primarily treats military uniform (7) :
BLA???L
19 In Holyrood push Ethiopia's money (4) : ?IE?
36 In Perth strips from time to time at library - ultimately shameless! (5):
?IR?S
DOWN:
7 Briefly submerge amphibious vehicle (4) : ?A??
10 Curiously listen absorbing essentially merry snicker in Glamis (7): L?I?TLE
18 Angle to strengthen with an iron plate (4): F?U?
29 In Glasgow we polish up local job centre (5) : B??O?

Matakari, glad you (+AB) are getting there. The thematic stuff is... child's play!

[Matakari]

Thanks, Toorak, Cashier! The thematic part is really child's play, indeed, NACW!
Just a confirmation for the following as I am having trouble parsing them:
12 In Reunion, white ordinary soldier primarily treats military uniform (7):
BLANCOS
15 King accepted wine essentially: tribute in the past (4): KAIN

[Neveracrossword]

Matakari, did you miss/forget the second post on the thread, for 12?
Yes to Kain. K, king, a, accepted + w(in)e, wine essentially.

[Matakari]

Many thanks again, NACW! For 12 I understood the part about white, but not the two-letter abbreviation.

[Neveracrossword]

Thanks, Matakari. As you had the answer and had typed out the clue again, I thought you'd work out that the O and the S came from (primarily) Ordinary Soldier. I'd have spelled that out if I'd realised you were still struggling to see it!

[Matakari]

It's quite clear now, NACW! This was really a nice workout!
