Javelin	This class gadget deal higher damage than the AT4 but it required lock time to shoot, and it can't target infantry.
Stinger	Stinger is similar to Javelin but deal lower damage and can't not target infantry.
Active Denial System	Active Denial System is a good class gadget for stealth playstyle to avoid getting spotted by enemies class gadget.
Anti-Tank Mine	Anti-Tank Mine is decent, it can disabled enemy vehicles when place correctly and triggers when the enemy drive pass it.

AT4 is the best launcher to use with the RM277, this launcher is very powerful to use for both vehicle and enemy troop with zero tracking time, player need to know how to measure the mid to long range shot.

Javelin and Stinger are the second best launcher that player can use, it can only target vehicle and require time to track, this required player to be further from the target so nobody spot them before launching to the target.

Active Denial System & Anti-Tank Mine & EMP Launcher are the third choice that player can equip, to utilize any of this class gadget player will become more of a supporter in the team instead.
