First and foremost: Thanks to the hivemind for helping with this!
Remember the first time someone screamed "BRDM! It's a BRDM!", at you and you had no damn clue how you were supposed to react to this? Or what to look for? The list of abbreviations is damn long (and this one by no means complete! If you see something missing, suggest it in the comments please! Missing an abbreviation but you're not sure what it means? Add it, too! Chances are somebody will fill it in) and I'm 100% convinced that nobody knows every single one of them. This list - click here for the entire one in alphabetical order - may prove itself helpful for some of the FNGs in the future.
Running away tactically retreating from something makes more sense when you know what the hell you're running from.
APC – Armoured Personnel Carrier
ATV – All-Terrain Vehicle
Before going over the list of amazingly alike sounding vehicles with the letter "B", take a look at the following picture. It provides a few useful points for telling them apart. Knowing what charges at you isn't the most unimportant thing to know.
BMD – Airborne amphibious tracked IFV
BMP – Amphibious tracked IFV
BRDM – Combat Reconnaissance Patrol Vehicle. A 4-wheeled lightly armored vehicle, with a turret on top, not to be confused with BTR-variants
BTR – Armoured Personnel Carrier. Has many variants, with some being deadly as fuck compared to others, for example BTR-80A has an autocannon on top
FV – Fighting Vehicle
IFV – Infantry Fighting Vehicle
MBT – Main Battle Tank
MRAP – Mine Resistant Ambush Protected vehicle (Also called “Battlebus”)
RAPTOR - Assault helicopter
