Numerically the most important U.S tank destroyer of WW2 combines high speed and mobility with a hefty 76.2mm cannon to form a well rounded tank destroying package.
The U.S. tank destroyer doctrine dictates mobility and firepower at the cost of armor protection. The M10 is armed with a hefty 76.2mm cannon and will pose a real threat to enemy tanks. It is known as the ‘Wolverine’ to the British, and simply as ‘TD’ to U.S. soldiers.

As with the M18 Hellcat, the M10 sacrifices armor for speed and mobility. Use this to your advantage when flanking the enemy, firing at their side and rear.
The velocity of the APCBC M62 round is 34% slower than the AP M79 Shot, and will thus arc more. Ensure to re-zero your sights when switching between the two.
The M10 does not carry a huge amount of ammunition, it may be advised to carry both APCBC and AP as backup instead of HE, when hunting tanks.
The M10 costs almost half as much to spawn that the M18. Consider spawning a M10 when facing weaker adversaries such as light tanks.
Due to the thin armor the M10 should not be played like a normal tank, but rather as a tank destroyer. I.e. avoid infantry hotspots such as capture zones, avoid open fields. Flank the enemy, relocate after a tank kill. Act from the shadows. An unaware enemy tank is an easy kill.
When engaging a strong enemy tank such as the Panther, it is advised to pause firing once the enemy starts turning their front towards you. Wait until they turn away before resuming fire.
The wrench is your best friend. make sure to repair your M10 whenever possible, for it is quite fragile.
Standing on top of your tank can make a good vantage point to see above bushes/ ridges using your binoculars.
