Lol. Wha's a real war? Vietnam war was not a war of equipment vs equipment this was a guerilla war and the only time US went up against NV hardware was when US launched air strikes against the NV. Vietnam war woke up the US military which was still a WW2/Korean war mindset of waging war. US was not built at the time to fight that kind of war.
Really sweetie , this is what wiki has to report on your losses. Take my advise you're better off Calling it a real war instead of a guerrilla war coz you come out of it much better otherwise it's a case of a rag tag bunch of underaged urchins beating the shit out of repeatedly begining with the Chinese in Korea , Viets in Vietnam & now the Afghans in Afghanistan.
United States Air ForceEdit
All told, the U.S. Air Force flew 5.25 million sorties over South Vietnam, North Vietnam, northern and southern Laos, and Cambodia, losing 2,251 aircraft: 1,737 to hostile action, and 514 in accidents. 2,197 of the losses were fixed-wing, and the remainder rotary-wing. The USAF sustained approximately 0.4 losses per 1,000 sorties during the conflict, which compared favorably with a 2.0 rate in Korea and a 9.7 figure during World War II.[9][10]: 268

The war Russia launched is the war they have been training for decades.
The SU collapsed in 1990 . Since then they've been picking up the pieces.
They are fighting a nation that uses old outdated soviet era equipment of which the Russian army should know like their back of their hands. There should be no excuse why Ukraine air force is still flying. No excuse why Russian air force can't fly over Ukraine due to Soviet era IADS.
There's still no logical reason why Russia hasn't brought it's full strength of the Russian Army to bear on Ukraine & is still conducting the entire operation with barely 1,00,000 troops. Let us know when you've figured this one out.
This is Russia's first "real war" since WW2 where they have to take on real mechanize brigades and enemy air space protected by IADS... they have completely failed.
Yes. As of now 20% of Russia is in Ukraine's hands & the war is destroying all of Russian infrastructure.
Desert Storm was the first "real war" the US fought since Korean war where they took on real battle hardened mechanize divisions and the second most dense IADS at that time and it wasn't even close. US totally dominated. US had to go half way around the world to expelled the 4th largest army that was dug in like an Alabama tick while Russia's war is just over their border.
Sure . The Vietnam war was a walk in the park . And Desert Storm with a coalition of 30+ countries & bases all surrounding I raq with 6 months to prepare for what ? Like it was Normandy & Omaha once again.
Russian military is and has been a paper tiger all along and relied on parades and combat exercises to make themselves look dangerous and competent. Ukraine war has exposed them for who they really are.
Allow me to let you on to a secret . Do let us know how many countries in the world can afford to deploy a 1000 fighter aircraft & all the supporting infrastructure & paraphernalia associated with it including ISR , refuellers , transporters , satellites , UAVs , etc churning out 4-5 sorties / aircraft / day with loads & loads of missiles of all hues , PGMs etc not for a few days but a few months without slacking in on intensity in any way & post your answer here .
