Weapons

The SDU has sufficient budgets that allow it to acquire up-to-date weapons. Due to this many foreign weapons companies aggressively promote their products to SDU by offering free samples. However the SDU has its own selection criteria, weapons that are not suitable for Hong Kong use, like M203 grenade launchers are not used. Rifles that have their bullets produced by only one supplier would not be chosen, for example the FN P-90 sub-machine gun (SMG). Besides guns described below, all SDU officers carry knives with them.
