The Army announced on 6 November — https://www.fbo.gov/notices/1b41bccca062afb27598326faae1e2a0 — that it is diligently working internally toward locking the [OMPV] requirement and finalizing its acquisition approach.
Once these are ready, the Army intends to release a draft RFP for Industry review and comment prior to the end of calendar year 2018.

The Government is now contemplating a longer proposal development period (greater than 3 months) and concurrent bid sample delivery (if required). The proposal and potential bid sample delivery will not occur any earlier than the beginning of 1QFY20.
