Don't fall for the "Unblocked 76" myth. Spend those 10 minutes watching The Shooting Range on YouTube instead, and wait until you get home to crew lock your favorite IS-2. Your K/D ratio (and your IT department) will thank you.
If you need an "unblocked" game of similar style, consider Shellshock Live (tanks, lighter) or Tank Trouble — but for authentic War Thunder , avoid unblocked knockoffs. war thunder unblocked 76
