Do you actually think there's a point in attempting to reach the center of Tikrit without massive airpower ? They've planted IED's everywhere, there's no point in losing that many people to bombs to free it. This isn't any different than the war in Grozny 1999, Russians leveled it which is the only solution for IS strongholds where no one from inside the city will give a helping hand. Same for Fallujah. The US leveled it with artillery and airpower in the 2nd battle ( 2004 ).
Read about the battle, Tikrit should be a similar operation, civillians left already.
Battle of Grozny (1999–2000) - Wikipedia, the free encyclopedia
The Russian strategy in 1999 was to hold back tanks and
armored personnel carriers and subject the entrenched Chechens to an intensive heavy artillery barrage and
aerial bombardment before engaging them with relatively small groups of
infantry, many with prior training in
urban warfare. The Russian forces relied heavily on
ballistic missiles (
SCUD,
OTR-21 Tochka) and
fuel air explosives. (The
TOS-1, a
multiple rocket launcher with
thermobaric weaponwarheads, played a particularly prominent role in the assault). These weapons wore down the Chechens, both physically and psychologically, and air strikes were also used to attack fighters hiding in basements; such attacks were designed for maximum psychological pressure.
