The community has created dedicated Firing Range mods (available via the in-game Workshop). These are premade trainers that feature:

You don't need a trainer to become good at Arma Reforger. You need deliberate practice. Here is a 3-week training regimen using only the in-game tools. Arma Reforger Trainer
A port of the classic Arma 3 trainer. This creates a white, empty VR space where you can spawn any item, vehicle, or enemy.
If you play on Official Bohemia servers, the situation is dire. With no active admins, trainer users run rampant. You will often see players with names like "User#####" sprinting across the ocean floor or one-tapping entire squads from the main base. The community has created dedicated Firing Range mods
The Community servers (like DarkGru, PBS, or Task Force Maple) are safer, but not immune. These servers rely on proprietary anti-cheat scripts and whitelisting. However, every time a server updates its scripts, the trainer developers release a bypass within 24 hours. It is a war of attrition that the volunteers are slowly losing.
Bohemia Interactive built the Enfusion Engine to be modular and modern. However, shifting from the legacy RV Engine (used in Arma 3) to a new architecture has opened temporary vulnerabilities. Search the Workshop for: "Training Grounds," "Firing Range,"
Because Reforger is essentially the testing ground for Arma 4, the anti-cheat measures (currently BattlEye) are playing catch-up. The server authority model is stronger than Arma 3, but many "trainers" exploit client-side authority for player position and collision.
The result? Community server admins are fighting a losing battle. Unlike mainstream shooters with automated kill cams, Reforger relies on admin spectating. But finding a cheater in a 128-player conflict match is like finding a specific needle in a stack of moving needles.
