Clip Teaser Call of Duty Vanguard appears online

In the midst of rumors about the opening of August 19, a brief teaser call duty: Vanguard has appeared online on Twitter.
With the launch date still has not been confirmed, it looks like Activision will have an ‘surprise’ announcement on August 19 or more leaks and information about the game will continue to flow in.
The teaser was recently distributed by MrDalejd’s Twitter users, which he claimed to come from.
Call of Duty team itself.
This is a 5-second long clip that shows a German sign that reads “attention”, a task force badge similar to the symbol of the special task force seen in the Call of Duty: WW2, World War 2 helmets, grenades and pistols (most likely Sten SMG).
Everything in the midst of the sound of a weapon that shot a very dense forest interspersed with a ditch, a barbed wire and fainted, something you would expect to be seen in the first-based man shooter 2.
Ummm …
I just sent this from @callofduty …
👀 “Front Western” https://t.co/69ekMPMTQC- JON (@MrdalekJD) 1628853886000We also get a glimpse of the type of warning for the fallen Sergeant Kingsley, who can become World War 2 Heroes David R Kingsley, Anumerta was awarded Honor medal because he saved the shooting of his plane who was injured by giving him his own parachute.
The teaser could be the first, among others to arrive before the announcement and trailer gameplay came.
However, there is no official channel about Vanguard.
Do we see D-Day and Tirfbornes? The inclusion of Sergeant Kingsley signaled several parts of the action that took place in Ploeşti, Romania, where the plane was severely damaged and several ships were injured by enemy fighters.
