20/20 is a term for Visual Acuity. Next year is 2020, and as a play on words, the proposal is for a build featuring visual observation as it's theme.
The Rules and Regs
Group build is proposed for any military vehicle, in any scale, that has a primary role in the observation (and reporting) task. The proposal is not for vehicles with offensive capability, but only for vehicles armed solely for self defence. Ideally only machine gun armed or at most armed with a weapon of no more than 20mm calibre:
- Artillery observation
- Radar operation
- Reconnaissance (centred on an intent to see and report, but not be seen or to openly engage the enemy)
- Fire control
- Command vehicles (not gun tanks that have dual roles and have an active offensive capability- tanks primarily designed with light weapons only to defend itself in need.)
