The Federal Reserve Unit (FRU) will be equipped with new weapons to deal with illegal rallies.
According to Utusan Malaysia, the FRU's new arsenal includes variable kinetic systems (VKS), tactical marking pistols (TMS) and flash launchers.
All three weapons fire pepper balls, which are similar to the pepper spray but are fired as projectiles.
FRU commander Wan Abdullah Ishak said the weapons are non-lethal and are better than tear gas.
"(They) are not dangerous against rioters, participants of illegal rallies and even our own personnel compared to tear gas.
"This is because with the weapon, it is easier to target specific individuals - like an aggressive rioter, without affecting other people and it is safe to use," he was quoted saying.
Wan Abdullah was overseeing the FRU new weapons training in Tampoi, Johor yesterday.
He said the FRU has acquired 140 TMP and five VKS and flash launchers respectively.
He added the numbers may be increased to serve the needs of 2,500 personnel across the country.
Kuala Lumpur will see the Bersih 5 rally scheduled on Nov 19, which is expected to meet counter rallies by pro-government groups.
Bersih is seeking Prime Minister Najib Abdul Razak's resignation over the 1MDB scandal, while his supporters have vowed to confront the rally.
Najib had denied wrongdoing or taking public funds for personal gain.
