Pros and Cons
- Good view range (only 10m less than the Chaffee)
- Light tank camo rating makes it a brilliant passive scout when equipped with a binocular telescope
- Excellent hp/weight ratio gives this scout tank good mobility and speed
- Nice penetration on the top gun
- Decent peek-a-boom flanker
- Can be lethal when put in a (rare) tier 6 match
- Poor armor, even for a light tank
- Low top speed for a high tier light tank
- Large target, twice to three times as big as its main counterpart; the AMX 12t, being much easier to hit
- Struggles to reach & maintain top speed
- Can be serious damaged by splash damage from artillery
- Outclassed in almost every way by the T20 (less HP, Barely any faster, Less armor, Worse Gun, Worse MM, looks uglier, etc.)
- Matchmaking can be very frustrating, resulting to be almost always the lowest tier with enemy tanks up to tier 10
- Poor camo rating for a light tank. Coupled with low speed, this tank cannot take up forward passive scouting positions without being spotted
The tank should be played in a similar manner to the M24 Chaffee. The only thing it lacks, is the Chaffee's amazing 76mm gun with 137 penetration, although the T21 has the same caliber gun with slightly less penetration, but the same damage output. Additionally, the Chaffee is a shorter tank, and a harder target to hit (although it has a very large and weak turret). To players used to the Chaffee this tank might turn out to be a surprisingly good vehicle. As another plus, the T21 has lower repair costs and more profitability than the Chaffee.
As with any tank, equipment improves the effectiveness of the T21. It is recommended to combine (or mix and match as preferred) equipment to these main playstyles:
- Scout: Camouflage Net, Binoculars, (choice is yours, recommend Coated Optics) In this role, you'll play more passive than active scouting. The T21 doesn't have the speed or low profile to play an active scout, so guerrilla tactics are important here; hence the Net and Binoculars.
- Flanker: Gun Rammer, Vertical Stabilizer (if you can afford it/steal it off another tank), [Gun laying drive/Vents depending on preference]. This will let you use that sweet M1A2 at will. Play always in and with support and you can lay some serious damage on the enemy. However, do be aware you won't last nearly as long as mediums do while trying to function in the same role as them. Coated Optics might help you if you choose this set up, as it allows you to become a deadly Artillery Hunter, finding and eliminating any SPGs.
- The QF 6-pdr Mk. III Gun and SCR 528 Radio carry over from the M7. Mount them immediately.
- Research the 76 mm Gun M1A1.
- Neither the 76 mm Gun M1A2 nor the Ford GAN Engine require the upgraded suspension, so research them in whichever order you want to.
- Finally, research the VVSS T48M1A2 Suspension.
