More durable as it is?
I don’t think, considering real factors, the both nations that operates the vehicles have totally different doctrines of war. As mentioned by a user here in the forums, the US focus on air superiority, which in-game are reflected by the vast options of ordnance weapons even in Fighter planes,
In other hand Soviet Union/Russia is the complete opposite, focusing on fast assault and in-ground combat, which is also reflected on the game with anti air systems more capable and this is why you’d see more Su-25 losses than A-10, documented,
In-game scenario people seems to underestimate the A-10 but I think they just don’t know how to operate the vehicle properly: Yesterday I was on Mozdok in a match and early on 2 A-10 was erasing our ground and guess what - no anti air.
This is also a problem between players, in a “team-based game” like War Thunder people have to leave their personal interests by side and focus on the victory of the team as a whole, what this means? Early SPAA players, God thank they exist but they’re rare to find, so rare that a guy just cursed some early SPAA players, and the consequences of almost no one plays as SPAA early match is saying on the forums “CAS OP!” and things alike,
In conclusion: No A-10 doesn’t need to be more durable because you can also shoot down a Su-25/K easily with a FIM-92K or E, the A-10 just need to be operated properly, in distance, let’s create a scenario:
“You got few players, you’re flying a A-10 to the battlefield, you got no bombs or weapons for supporting ground but you don’t want to return to the airfield and lost a precious times getting more kill; you see a T-80B, T-72B (1989) and a BMP-3 with no anti air support near by, which are you choosing?”
If you choose the hardest target (T-72B (1989) you’ve been shoot down by the BMP-3 at this point, despite the slow firing rate cannon, the A-10 also shares this problem the slow flying speed, in this case you strafe and destroy first the BMP-3 then return and disable or destroy if possible one of the two remaining targets and eventually will be destroyed by a ally in ground.
In this scenario is something that I’ve seen during matches when saw a average A-10 player: focusing on not important targets that won’t be a threat for their capability of begin alive, let’s say by that, and sometimes not even killing the target if using the 30mm cannon because most of the time they’re using the AGM-65 bombs and returning to the airfield to restore and bomb them again and again which I don’t blame, it’s a tactic you are free to use this.
I’m sorry if it was too long of confusing but I really got out of hand mixing some real factors with the game.
