The Border Incident
War Medal
国境事変従軍記章
This medal commemorates the Nomonhan Incident, a clash with Russia that happened in Manchuria.

The medal is a yellow bronze. The attached bar says 'War Medal.'

OBVERSE: Pu-Yi's orchid crest is above. In the center is a dove with outstretched wings. Below is part of
the globe showing Asia. Also clouds and rays.
REVERSE: 'Border Incident.'

According to Peterson, there is a rarer variant with slight differences, the main one being the dove is
thinner. Although he is correct on there being a variant, I am not sure it is so much rarer. In fact, I have
seen many more 'rarer variant' medals than the regular one. So perhaps until more information is
available, the thin dove should be variant 1 and the fat dove variant 2. Both are pictured below.

The other major differences can be seen by contrasting the orchid crest above, the clouds, and the
globe/map below. The differences are easy to spot.
