Update: according to a reader, light tanks are built for brawling and are amazing at yoloing... Please disregard all content of my guide.

Prologue:
So, lights have weak guns and paper-thin armour; most players have had bad experiences of this first-hand, and most new players ditch them to go for the heavies. This is true for me after my encounter with the MT-25 - as a new player back then, I saw the thing as a pile of scrap (and it pretty much still is). However, I persisted with learning light tank strategy, taking in the information supplemented to me via guides on youtube and the WoT blitz forum, and I recommend that the readers of this guide do the same.

However, returning to lights, the keys to these fast little buggers are:

To abuse your speed while not running into the line of fire. This, my friends, would be called NOT YOLOING! (I see so many people ignore this commonly overstated tip!)

To keep people spotted; proximity-spot or simply using your often comparatively massive view range.

Treat a hit like a death, this helps to maintain a mindset of preservation which you REALLY need for this kind of tank. (You can still keep this mindset even for the armoured lights, the T-54 lightweight and the LTTB)

Dima's tip time:

Go for as much bias as possible! Even if it means selling your soul to the devil to get past the awful MT-25, DO IT!

NEVER attack a heavy or even a small group of meds frontally, BLIN, even if your C Y K A comrades got into trouble! Even ♥♥♥♥♥ bias won't help you with this if you do it!

If your urod comrades have gone to babushka's holy vegetable patch, use Stalin's gift of many speeds to get you as far away from the capitalists as possible and capture the bases to change those kurwas' minds!

Finally, use the gun that the semechki-eaters in the plant gave you in the end game! if there are max. 2 enemies left, use your slavic speed and beat the B L Y A T out of the cykas' sides! That will give them a very lethal dose of communism!

Conclusion: NOOBS DO NOT PLAY THIS TYPE OF TANK BEFORE YOU HAVE READ THIS OR OTHER GUIDES FFS I'M TIRED OF ALL OF YOU YOLOING AND DYING IN THIS FIRST MINUTE!
