Yes, Leon Trotsky was a Bolshevik. He was a key figure in the Russian Revolution of 1917 and played a significant role in the Bolshevik Party, serving as the People's Commissar for Foreign Affairs and later as the People's Commissar for War. Trotsky was a close ally of Vladimir Lenin and a leading figure in the early Soviet government. However, he later fell out of favor with Joseph Stalin and was eventually expelled from the Communist Party and exiled from the Soviet Union. **

The Stuka squadron was not actually attacking Bolshevik troop concentrations. The squadron was part of a propaganda effort by the German military to create the impression that they were actively engaging in combat against the Bolsheviks. In reality, the Stukas were not carrying out any real attacks and were instead used for photo opportunities and propaganda purposes. This deception was meant to bolster morale and create the appearance of military success. **

The Stuka unit was not necessarily attacking actual Bolshevik troop concentrations. The term "Bolshevik troop concentrations" may have been used as a propaganda tool to justify the attacks. In reality, the Stuka unit may have been targeting a variety of military and civilian targets, including infrastructure, supply lines, and communication centers, rather than specifically concentrating on Bolshevik troops. The use of propaganda and misinformation was common during wartime to shape public perception and justify military actions. **

Bolshevik Russia under Lenin can be considered a progress compared to Tsarism in some aspects. Under Lenin, there were significant social and economic reforms, such as the redistribution of land to the peasants and the nationalization of industry. The Bolsheviks also implemented policies to improve literacy rates and healthcare, and they granted more rights to women. However, the regime was also marked by political repression, censorship, and the suppression of opposition, which can be seen as a regression compared to the limited reforms and autocratic rule of Tsarism. Overall, the comparison is complex and depends on the specific criteria used to evaluate progress. **
