You don't say how many.
Assuming about a dozen or so, get hold of
some Upholstery Nails (actually long pins,
mine are 47mm long). Squeeze the tip between
a pair of pliars, stick on a pennant (paper) &
(if you want) build up a 'cone' to protect the hand
with, putty, glue etc.
As to the shields:-
Raid any existing/stashed away transfer sheets.
See what transfers are available cheap on e-bay.
Many can be trimmed down and made useful.
e.g. Hoplite, Fantasy, Bomber nose art even.
Hope this is of some use.
