you can often disable a tank in 1 shot but not kill, if it takes 2 shells for a kill with the fireflys reaload thats of 5.9 seconds for 5 shots (ready rack) which is 1 kill every 11.8 seconds, with that decreasing to (with i think it is a 1.5x reload multiplier) a kill every 17.7 seconds, the M4A3 has APHE and can still pen most of what it faces when in the same lobby as the Firefly (4.7-5.7) and has the same reload as the Firefly, at 5.9 seconds, so it can kill a tank evert 5.9 seconds, In addition it doesnt have a ready rack, so it can keep that 5.9 secodn reload for all 71 shells,
this matters cuase you can move onto the next target quicker, sitting there reloading to kill a target leaves you open to being shot by someone else you couldve shot if you didnt need to take 2 shots to kill
meaning that the US 75 and russian 76mm cannot pen it without aiming for much smaller weak spots
75mm M3 M61 Shell : 104mm Penetration
17 Pndr Shot Mk.8: 190mm penetatration
Almost Double, Not Triple, if you are talking about the 17 Pnder APDS with 269mm pen, the firefly doesnt have that (bar the Italian one at 5.0) even then thats ingoring the woes of the 76mm APDS which either does no spall or just shatters
he says as he has a 1.21K/D in the M4A3 at 5.7 and a 1.2K/D in the 4.7 Firefly, meaning you do better in the M4A3 … a whole 1.0 Higher
And the Firefly haas the alrge wweak spots and APHE, shoot at the heatches and its a one shot for the M4A2 and has a 5.0 second reload top, and a short stop, while yes the 17 pounder is fairly efficient as dealing with shermans and will probabally kill in 1 shot aswell the time it takes for the gun to settle means the M4A2 could squeeze a shot in and kill the firefly before hand, but in the end, these are seperate BRs for a reason and a direct comparison 1v1 is by no means representative of the greater game senario, like the T-50 and Archer, yes the archer has the 17 pounder and at the same BR the T-50 is better in pretty much every way and much more useful in the game senario
