The military will also shorten the quarantine period for service members returning from their vacations by three days to a week to minimise its burden of handling Covid-19 patients.
The military added it plans to prioritise PCR tests for high-risk members should the omicron infections overwhelm its testing capacity.
"The Defence Ministry will continue efforts to maintain a robust and unwavering military readiness posture by thoroughly implementing antivirus measures, while ensuring the basic rights of the troops," the Ministry said in a statement.
While no new restrictions on vacations or off-base trips are planned for now, the military added it may roll out intensive social distancing measures should the virus affect its mission capabilities.
