They are there as a dry run for Trump's use of the military to seize voting equipment and records during and after the November 2026 and 2028 elections.
After it was clear he lost the 2020 election, Trump demanded that then Secretary of Defense Esper and Attorney General Barr use the military to seize voting equipment and records.
An executive order was drafted in December 2020 citing phony claims about election fraud and voting machines. The order, complete with a dotted line ready for Trump's signature, directed the SECDEF to "seize, collect, retain and analyze all machines, equipment, electronically stored information, and material records required for retention" under a law that relates to preserving election records. Fortunately, Esper and Barr stood firm and Trump backed down.
Today, the SECDEF and AG are Trump toadies who are partners in his scheme to end free elections.
Earlier, several times on the 2024 campaign trail, Trump told his audiences to vote in 2024 and you wont need to vote again. Now we are seeing his scheme come together -- this is just practice.
